The Role of Organizational Commitment on Organizational Citizenship Behavior in Hotel Industry

There are many studies that focused on the role of organizational commitment on Organizational Citizenship Behavior (OCB) specifically conducted in Indonesia. However, few of studies emphasize on the role of three conceptual constructs of organizational commitment namely affective, normative, and continuance on OCB in Indonesian context. Several empirical studies still remain inconclusive due to the inconsistency results. This research is intended as an empirical test to examine the role of three conceptual dimensions of commitment on OCB, and also tested to add body of knowledge about the results of this empirical study in Indonesia especially in hospitality industry. This is a quantitative causal research with 73 three-starred hotels’ employees as the respondents. The data is processed using SmartPLS 2.0 as the statistical tools, and as the result it is found that affective commitment affects positively and significantly toward OCB; normative commitment affects positively and significantly toward OCB; and lastly continuance commitment affects positively and significantly toward OCB.


INTRODUCTION
Until present, there are still many studies that emphasized on the role of organizational commitment specifically in its increasing role to enhance Organizational Citizenship Behavior (OCB). Organizational commitment could be defined as the willingness of employees to maintain their membership in an organization (Allen and Meyer, 1990). Organizational commitment is divided into three conceptual dimensions known as affective commitment, normative commitment, and continuance commitment (Allen and Meyer, 1996).
Studies that have been conducted based on the role of organizational commitment towards enhancement of OCB specifically conducted in Indonesia, mostly only focused as an unidimensional concept (Fanani et al., 2016;Rini et al., 2013;Widyanto et al., 2013). While studies that specifically focused on the role of each conceptual dimensions in a multidimensional manner are yet not widely conducted.
Empirically, several studies that have been conducted still remain inconclusive due to the inconsistency results, in explaining the role of each dimension towards the enhancement of OCB (Addison et al., 2006;Bakhshi et al., 2011). Previous study that conducted by (Addison et al., 2006) showed that affective commitment does not impact on the enhancement of OCB, while the result from (Bakhshi et al., 2011) showed that continuance commitment does not impact on the enhancement of OCB.
The conceptual insight by (Meyer et al,, 2002) argued that the three conceptual constructs of commitment could have a different effects on OCB, whereas affective commitment could affect positively towards OCB; normative commitment could affect positively towards OCB; and continuance commitment could affect negatively or totally have no effect towards OCB (Meyer et al., 2002).
OCB as an unique behavior could provide with different colors for the organization, through its extra behaviors that are shown as voluntarily act to provide additional benefits fot the organization (Podsakoff et al., 2000). Through its extra behavior shown by employees, it also provides hegemony in particular behavior within the organization that could also lead to better productivity performance, and even better financial profitability of the organization (Nawaser et al., 2015). Several studies that have been conducted on the role of antecedents originating from employees' within to enhance OCB have been conducted, for example, the role of employees' motivation towards OCB (Febriani and Saleh, 2019;Kumar and Prabakar, 2016;Hasanah and Suriansyah, 2019); individual job satisfaction towards OCB (Musringudin et al., 2017;Saxena et al., 2019;Prasetio et al., 2017). While the role of organizational commitment to enhance OCB in the context of hospitality industry is still few, except the studies of (Kim et al., 2020); (Yeh, 2019); and (Tan et al., 2019).
It is undeniable that in the tourism industry and specifically the hospitality industry, still faced with the classical challenge of employment and sustainability. (Baum et al., 2016) argues that related to human resources, the hotel sector in particular still encounters many diverse and complex constraints such as challenging working conditions; jobs that tend to be difficult; low pay levels; opportunities for gender and minority; high turnover rates; and employee personal problems. This is both directly and indirectly affected by the policies set by each management. Thus, the impact also varies both positive and negative. In Indonesian context, the challenge is also happened specifically in the hotel industry. (Suryani, 2017) stated that although the absorption of labor was quite high, however, the conditions of the employees were still apprehensive due to management's discreet selective decision in appointing permanent employees. Therefore, it has impact on employees' psychologist factor which could then have impact on the commitment shown to the organization as well. Due to the high level of uncertainty for employees, this condition could appears to be an inconvenience concern at work, and obviously it would also impact on employees' commitment to the organization (Osman et al., 2017). Moreover, this condition also has an impact on improving employees behavior to be willing to make extra efforts that could provide benefits for both employees and organization.
This research is intended as an empirical test to examine the role of three conceptual dimensions of commitment by (Allen & Meyer, 1996) toward OCB, specifically tested to add body of knowledge about the results of the empirical studies in Indonesia especially in hospitality industry. At present, there are quite a lot of studies conducted in the hospitality industry due to its uniqueness that needed to be highlighted in the industry, which of its service oriented and quality oriented provided to its customers (Bernice et al., 2015). Therefore, the extra behavior is required which is voluntarily expressed to provide excellence service for its customers. Based on the empirical study, there is an interesting result that commitment shown by hotel's employees is inadequate to have an impact to OCB's enhancement (Kartika et al., 2017).

THEORETICAL REVIEW
Organizational Commitment. Organizational commitment to date has been conceptualized in variety contexts, all of which point to the employees' emotional attachment towards organization. Conceptually, the development of the construct also grows from unidimensional construct, to a much more complex and complete construct, namely (Allen and Meyer's, 1990) three conceptual model of organizational commitment (Agarwala et al., 2020).
Many academic scholars who often clarify the connection between employees and their organizations as a reciprocal relationship, whereas between each of them often occur both economic and socioemotional exchange. In its implementation, employees often see it only from tangible perspective such as pay or benefits, whereas socioemotional exchanges are often seen as intangible, which could only be felt by employees such as care and trust from the organization (Liu et al., 2018). According to (Allen and Meyer, 1996) organizational commitment is a psychological construct which characterized a connection between employees with their organization that contains implications toward decision for employees to maintain or not their membership within organization. Organizational commitment is considered as a working attitude that reflects employees' feeling whether like or dislike the concurrent situation. Therefore, when employees reflect their high commitment to the organization, the more they will give extra effort to support the organization.
Organizational commitment has conceptual constructs namely affective commitment; normative commitment; dan continuance commitment (Allen and Meyer, 1996). In more detail, affective commitment is a commitment that stems from the personal desire to continue working in a organization due to the similarity between the objectives and values of the organization wiht personal goals and values. Employees who have a superior affective commitment tend to help and support the organization in achieving its goals (Greenberg and Baron, 2008). Affective commitment is often relevant to voluntary, closely related to motivation that comes from the job itself, not related to monetary matter, and socioemotional needs arise from personal positive experiences that have been experienced previously during conducting the job which is voluntarily by giving time, energy, and knowledge for the shake of organization (McCormick and Donohue, 2019). Affective commitment and normative commitment are concepts that closely interrelated, both of which contain moral elements and attitudes as a form of involvement and identification of closeness towards organization's value and its goals, and also emotionally reflected between employees and their organization (Devece et al., 2016).
Normative commitment is a commitment that originates from the employees' feeling to be obliged and stay in the organization due to external pressures. An employee who has a high normative commitment will tend to concerned about what others think for the decision to quit from the organization. The higher an employee's normative commitment, the worried the employee will be regarding what others think and how disappointing it could be. The employee will develop self-perception about how bad the decision if decided to leave the organization (Greenberg and Baron, 2008). Normative commitment is a part of personal that is often perceived as "obligation to stay" which also has a relationship with "moral obligation". Often the application in real conditions is related to the motivation of personal motivation as a natural bonding to the organization. Specifically, if it is connected to individual values that view loyalty as the most important thing in doing work (McCormick and Donohue, 2019). Normative commitment can reflect employees' sense of morality about how they should deal with obligations towards their organization, which is reflected in the feeling of being indebted to organization for the services that has been provided and reflected in moral responsibility to stay in the organization (Jaros, 2017).
Continuance commitment is a commitment that arises due to an employee's desire to survive in organization because of security reason. The employees urge to stay due their inability to do their things outside the organization. The longer employees stay at the organization the more employees feel worried about losing what have been invested in the organization while being members of the organization. Thus, this commitment appears as a form of necessity to survive rather than leaving the organization under uncertainty condition (Greenberg and Baron, 2008). Continuance commitment owned by employees contain two main elements, namely "high sacrifice" where employees will often think of the advantages and disadvantages that will be obtained during their presence in the organization or resign from the organization. While the other, "low alternatives" where employees are often in a position of few or even no other choice at all to decide whether to stay or leave to choose another organization that is considered more profitable (Devece et al., 2016).

Emotion-based commitment
Obligation-based commitment Cost-based commitment I feel comfortable with coworkers, which makes it hard to leave the organization My superior has invested a lot of time in guiding me, and providing training for me The organization promises promotion that will be done soon, will I get the same chance if I move to another organization? I feel comfortable with the current working atmosphere that makes me happy and comfortable My organization has provided me with opportunity to work while Compensation provided by my organization is sufficient to live in the others are doubting my abilities a better approriate place which requires high cost of living I feel satisfy with the tasks given by organization, so I enjoy doing my daily job M superior has helped me when I am in trouble, which make me reluctant to withdraw from the organization Getting a job and good education system, makes it comfortable to stay at the organization The reason to stay in the organization because of desires from within The reason to stay in the organization because I feel that I should maintained to stick out in the organization The reason to stay in the organization because of necessity Adopted from (Colquitt et al., 2011) (Greenberg and Baron, 2009) argues that employees with higher organizational commitment will have different behaviors. However, it would also provide with some additional benefits for the organization, including: (1) Committed employees are less likely to withdraw. Employees who are highly bonded to their organization will tend to be less likely to absent from work or even the worse action which lead to resignation. High commitment is also related to personal satisfaction when working in the organization and the satisfaction to work cause no reason to leave the organization. (2) Committed employees are willing to make sacrifices for the organization. Employees who are highly bonded to their organization will show a great desire to work and also to some extent willing to make the sacrifices needed by organization to develop and achieve organization's goals. This condition is somewhat very important during modern times like present, where the world of technology has become more advanced, and employees are expected to be able to working in extended long hours.

Organizational Citizenship Behavior (OCB).
After studied for more than three decades, the concept of OCB continues to be a prominent topic of discussion among scholars, whereas the development is considered important for managerial implications, behavioral studies, and also psychology context (Rose, 2016). OCB is an extra individual behavior that is explicitly not included in a formal job description, but its overall can improve the organization function's effectiveness (Organ et al., 2006). Employees can contribute to their organization by showing positive behaviors in helping coworkers, volunteering to do work beyond their responsibility, and complying with organization rules and procedures. Voluntary behavior could provide a positive added value as a social behavior that aims to help others.
In its journey OCB developed into a more mature concept and experienced a comprehensive formation from scholars that specifically focused on individuals and in relation to the organization in more general context. Development of definition and its attributes have been enriched from time to time (Rose, 2016). Therefore, it is no doubt that the development of the nature of OCB needs to be developed rapidly and continuously especially in its relation to a broader and more complex context. Likewise with the development of the OCB concept, one of which was developed by (Williams and Anderson, 1991) whereas the development of the OCB construct was based purely on the construct that was first introduced by scholars before them (Organ et al., 2006). It shows the rationale of the OCB concept which is not out of the mainstream of thought that assumed behavior as voluntary and conducted in order to provide help to others.
The basic philosophy that later became the cornerstone of OCB's development stems from a story in biblical passage that is often known as "the good samaritan" whereas in principle, someone who should never meet and know each other before, could provide help and assitance that obviously should be none of their main concern that should deserve a top priority. However, in reality the help and assistance was still provided event without the expectation of getting a proper reward (Organ et al., 2006). In the more modern day conceptual thinking, relation between employees and organizations are often more prone to be transactional, or some context suggested, it leads to a social exchange between both of employees and organization (Liu et al., 2018). (Organ et al., 2006) argues that OCB can provide several benefits for the organization including: (1) Increase the productivity of employees through helping behavior among other, for example by provide help during orientation period for new employees; and helping other employees in completing task that has entered deadline period.
(2) Give employees the freedom to do their own work, give managers more time to do their works, and also promote collaboration in teams as general or specific taskforce. (3) Recruiting and retaining employees who have behaviors that are in line with company values by producing and preserving a comfortable and friendly environment. Hence, the employees will feel more comfortable and also increase their sense of belonging. (4) Create social networking through a better communication and building strong networks between employees horizontally and vertically in order to improve efficiency in communication method and information exchange to minimize errors in the process of information delivery.
OCB that stated by (Williams and Anderson, 1991) consists of two main dimensional attributes namely OCB towards individual (OCB-I) dan OCB towards organization (OCB-O). OCB-I is an extra behavior aimed at individuals in organization that can include coworkers, superiors, or subordinates in the form of providing help for work overloads or help due to specific individual reasons. OCB-O is an extra behavior aimed at the organization as a whole that could benefit back to organization.
Affective commitment is a key factor to predict OCB (Meyer et al., 2002). Affective commitment could arise because of employees' desire to remain their membership in organization due to the similarity of goals and values. This alignment could further support in organization's goals achievement. Hence, with goals and values alignment between employees and their organization could attract the employees' willingness to show an extra behavior toward their environment. The higher personal alignment towards organization could lead to higher extra-role behavior (Meyer et al., 2002;Organ et al., 2006). Associated with social exchange framework, when employees have an emotional connection with organization, they will tend to bring more reciprocal behavior by showing extra-role behavior that could benefit them (Lee et al., 2018). Previous empirical studies indicate that affective commitment affects positively and significantly towards OCB Lee et al., 2018;Paramaartha et al., 2019;Afandi, 2019). Therefore: H1: Affective commitment affect positively and significantly towards OCB.
Normative commitment is the feeling of employees who feel obliged to commit and stay in the organization because they are concerned about what others would say when they Affective Commitment

Normative Commitment
Continuance Commitment OCB leave the organization (Greenberg and Baron, 2008), therefore this burden of obligation shapes the employees' commitment. When the employees have a high normative commitment, there will be an obligation for the employees to play in a major role to achieve organization's advantages. Thus, extra-role behavior will be formed due to the obligation to ensure the advantages of the organization as a form of obligation that should be performed and done (Addison et al., 2006;Bakhshi et al., 2011;Meyer et al., 2002). The previous empirical study's result, indicates that normative commitment affects positively and significantly towards OCB (Genty et al., 2017). Therefore: H2: Normative commitment affect positively and significantly towards OCB.
Employees who have high continuance commitment will decide to stay in the organization not for emotional reasons but for considering the losses and benefits that might be experienced if they decide to leave the organization. If the employees then decided to stay in the organization, the longer they stay, the more negative cause will happen and adverse effects (Allen and Meyer, 1996). Therefore, the higher continuance commitment would lead to less initiative efforts and positive behaviors, and conversely would cause a detrimental to the organization for a longer span of time (Meyer et al., 2002). Therefore:

METHODS
This research is a quantitative causal research that its goal is to explain causal effect between studied variables. The exogenous variables in this research are affective commitment (Affective); normative commitment (Normative); and continuance commitment (Continuance); and the endogenous variable is OCB (OCB). This research is conducted using employees who work in three-starred hotels in Makassar City, South Sulawesi. Purposive non-random sampling method is used to gather the data, as the employees are considered as permanent employees and have been worked for more than one year, with the total samples are 73 respondents. Questionnaire is used as a data collection tool with Likert scale ranging from 1 (one) as totally disagree to 5 (five) as totally agree.
The indicators used for organizational commitment refer to the indicators used by (Allen and Meyer, 1996) with its adoption content in term of hotel industry context. It consists of eight-item indicators for affective commitment for example "I feel the hotel's management and people in it like part of my own family"; six-item indicators for normative commitment for example "I feel that I have an obligation to stay to work at this hotel"; and nine-item indicators for continuance commitment for example "My life will be screwed up if I decide to resign from this hotel now". For OCB's indicators are adopted from (Williams and Anderson, 1991) that consists of eight-item indicators for example "I don't want to complain about unimportant things about my working condition".

RESULTS
Data processing begins with processing descriptive data that includes gender and age by using frequency distribution calculation derived from all respondents used as research data with total of 73 respondents. Descriptive demographic in detail could be seen in table 3. The data processing uses SmartPLS 2.0 program for model test and hypothesis test. Based on table 4, the results of processing validity test are obtained by looking at the loading factors for each indicator items, which is related with convergent validity which has the principle that indicators between developed constructs should have high correlation (Abdillah and Hartono, 2015). The prequisite value for loading factor to be considered as valid with the amount of loading factor value greater than 0,5. Hence, indicator X18 and X39 do not meet the requirements to be categorized as valid. Consequently, these two indicators will be dropped and will not be included for further process. The data process is continued by conducting the second phase of validity test by checking the loading factor value. As shown by table 5, the overall value of loading factors have been greater than 0,5. Hence, all indicators are considered as valid. The validity test is continued by conducting discriminant validity test, by looking at the AVE root value with cut-off value gerater than 0,7. As argued by (Abdillah and Hartono, 2015) that the indicators that form different constructs should not have high correlation such as indicators of exogenous variables with their endogenous. Therefore, based on table 6 it is shown that all variables are pass the cut-off value of discriminant validity and could be considered as valid.

Fig 3. Research Model Final
For the reliability test, to be considered as reliable the cut-off value of both composite reliability and cronbach alpha should be greater than 0,7. The result from table 6 indicates that the reliability value for the overall variables are greater than 0,7. Hence, all variables are considered as reliable. The last phase during the data process is to test the hypotheses to get proof of the research study that has been proposed. Hypothesis testing is conducted by observing at the original sample value to find out the direction effect whether it is positive or negative, and by looking at the T-statistic value to find out the significance of the effect produced. As a reference direction, if the original sample value shows a positive value, thus, the direction effect could be considered to be positive. Conversely, when the original sample value shows a negative value, thus, the direction effect could be considered to be negative. For significance testing is performed by observing at the T-value compared with the value of 1,96. If the value of T-value is greater than 1,96, it could be said that the effect is significant, and if the value of T-value is smaller than 1,96, it could be said that the effect is not significant. Table 7 shows that affective commitment affect positively and significantly towards OCB; normative commitment affect positively and significantly towards OCB; and continuance commitment affect positively and significantly towards OCB. Therefore, hypothesis 1 and 2 are supported, and hypothesis 3 is not supported.

DISCUSSION
Based on the demographic data of the respondents in table 3, it shows that the majority of respondents are male (61,6%) with the majority of ages being in the range of 18-25 years old (82,2%). The result show that the average respondents are in the productive age which makes it possible to work effectively through a full-time job. There is a tendency that during the productive age, employees can feel stable and productive conditions in earning income. However, it also creates a tendency to have financial responsibility at least towards closest kins or relatives (Kartika et al., 2019). Although descriptive data does not explain in detail and only explain basic number explanation especially regarding the role of employees as breadwinners, the condition could lead to a more comprehensive tendency regarding the ability of employees in order to survive in the organization which also affect their behavioral tendencies to survive and remain in the organization. Thus, it is plausible for the employees to perform different behavior which is dependent on specific condition from each of them.
The result of this research shows that the higher individual's affective commitment, the higher OCB displayed by the individual. The result supports the previous study by (Meyer et al., 2002); (Organ et al., 2006); ; (Lee et al., 2018); (Paramaartha et al., 2019); and (Afandi, 2019) as an additional empirical support. When there is an alignment between goals and values that belong to employees and organization, it could creates harmony and it will unite the goals and the values altogether. This condition could leads to enjoyment and enthusiasm by the employees to achieve a common goal during their existence in organization. The pleasure that is generated could have an impact on willingness and initiative to show certain efforts in achieving organization's goals. This kind of unique efforts are raised as the manifestation of the extra-role individual behavior within the organization.
Affective commitment in this study is reflected through the indicator "the pleasure of talking about organization with colleagues". As the implication in this research, when employees feel the pleasure that is obtained during their presence working in the hotel, the employees will tend to talk about positive things that they have experienced during their day-to-day operational. Consequently, the pleasure of the employees during their existence in the hotel will further increase the willingness to show positive extra-role behaviors for the hotel.
Normative commitment affect positively and significantly towards OCB, it means that the higher individual's normative commitment, the higher OCB displayed by the individual. This research supports the arguments by (Greenberg and Baron, 2008) and also the empirical studies by (Addison et al., 2006); (Bakhshi et al., 2011); (Meyer et al., 2002); and (Genty et al., 2017). When employees feel to maintain their membership in the organization as an obligation, whether like it or not they would continue to do it. This condition is also supported when the employees are too concerned about what others will say rather than what they feel for themselves. The concern over what other peoples' thoughts and feelings, could creates obligation for employees to participate and encourages further bigger obligation in achieving organization's goals. Therefore, extra-role behavior will arise when the employees feel that it is their duty as members of the organization to show more effort for the success of the organization.
Within this study, normative commitment is reflected by the indicator "the organization deserves my loyalty". When employees feel that the hotel deserve their loyalty, the employees will voluntarily provide the best effort for the development of the hotel. As the employees who feel that their hotel as a place of work deserve their loyalty, then the employees will increse their efforts to develop the hotel's advantages.
Regarding the continuance commitment, the result shows that continuance commitment affect positively and significantly towards OCB. The result does not support and shows contradiction against the previous study (Meyer et al., 2002). As the implication shows that the higher continuance commitment will lead to the higher extra-role behavior showed by individuals. The results indicate when employees decide to stay in the organization due to consideration of losses and inconveniences that might be obtain when they are leaving the organization, it could actually make the employees rely on their individual extra-role behavior, in order to survive and remain at the organization.
In this study, continuance commitment is reflected by the indicator "unavailability of vacancies elsewhere". This result indicates that when employees create perception that the availability of job vacancies elsewhere is higher, it will also increase continuance commitment. With the incremental in continuance caused by the lack of opportunities to work in other places, it makes the employees within organization to try to show positive behavior in order to generate positive opinions to maintain their membership in the organization. In the context of this research in hospitality industry, the higher continuance commitment is due to the lack of availability of working opportunities elsewhere which then force employees in the hotel to try to maintain their presence in the hotel by increasing the hotel advantages through positive extra-role behavior shown.
Business atmosphere of the hospitality industry in Makassar city still shows a downturn, which is caused by external factors such as the high price of airplane tickets, and the uncertain political situation that makes business direction still unclear as well (Ristyaningrum, 2019). This condition has also hampered the development of the hotel business, which in turn has limited employment opportunities, especially in starred hotels. The condition later became the basis of the high continuance commitment in starred hotels in Makassar city. This phenomenon is the basis for employees to compete to show their best efforts through extra-role behavior in order to maintain their existence in the hotel where they currently work. This condition also requires employees to think more actively, especially when they begin to anxious about the possibility of remain at the hotel or not. Thus, the extra efforts will be shown as a form of anticipation (López et al., 2017). This justification could be supported by the previous descriptive data showing that the majority of employees are in productive age who have a tendency to be breadwinners, as argued by (Kartika et al., 2019). Hence, employees tend to have pressure to remain in the organization as their condition required to do so, by taking actions that are considered to able to give a positive impression from management perspective, which one of it by showing OCB in order to remain in the organization.
In the context of this study, culture has a tendency to play a role in shaping employees' behavior. (Thio and King, 2017) suggested that hotel employees who have high work value can have an impact on organizational commitment. However, perceptions that arise over the value held by employees could be formed due to several factors especially those obtained from the organization's active role that oversees employees. One of the prominent factor that emphasized to the result of this study is the extent to which employees get certainty for the work done at present time (job security). Points that specifically emerge from the outside employees' personal but yet precisely have an important role in ensuring employees to enhance their work value. Thus, if it can be aligned with the organization's values, then it would give a prominent impact which benefits both the employees and the organization (Thio and King, 2017).
Moreover, employee culture provides a rationale for how employees form perceptions of the exhibited behavior, whereas there is a tendency that Indonesian people tend to avoid conflicts and will try to find solutions by compromising or negotiating, despite their personal pressure from their closest environment such as inner family or extended family. Hence, it forms the tendency of each individual to thrive to survive in the organization without having to open conflict with other employees. However, it does not mean it always done correctly and in accordance with applicable ethical behavior. The argument is also as a justification for the differences that arise over the overall employees' behavior in the western culture context and Indonesian culture context. In the western culture context, employees with higher continuance commitment will tend not to show OCB (Meyer et al., 2002). However, in the Indonesian culture context as the contrast result that employees with higher continuance commitment will tend to thrive to remain at the organization by exhibiting OCB as their solution to keep remain in the organization.
The study results also prove that affective commitment is the most dominant factor in the formation of OCB. These results also support previous studies which also show the same empirical result which show that OCB can be formed through the existence of high affective commitment (Meyer et al., 2002;Organ et al., 2006, Lee et al., 2018. Employees with higher emotional ties to their organization will tend to make their voluntary contributions to the success of the organization. Higher emotional ties can be caused by the similarity of values and alignment that arise between employees and their organization. This condition can be considered as "the best scenario" that could make organization run smoothly during its effort in achieving its goals. (Liu et al., 2018) provides a description that the emotional bond that formed between employees and their organization can be a reciprocal positive behavior which then also leads to benefit for all parties.
In its managerial implications for the hotel industry, it could be concluded that within macro conditions which are often beyond the individuals' control, it could indirectly increase the competition levels among employees both internally within the hotel, and among employees at different hotels which sometimes explicitly, it could trigger several severe problems among employees. However, the condition could be "double-edged blades" that provide advantages as well as disadvantages. Firstly, for hotel management perspective this condition could encourage a rapid incremental in employees' motivation and effort to perform their job optimally to avoid leaving or forced layoff from the hotel which indicated far less favorable for employees. On the other hand, the condition could also interfere with organizational stability caused by unfair competition among employees, or even use any means that are not commendable (Chen et al., 2016). Secondly, hotel management could project the employees mapping to find out the best employees currently owned for the shake of long term consideration for the organization's sustainability in the future. However, there is also the potential for the hotel management to identify the current condition whether the organization has adequate employees or not as the basic consideration for management and provide an illustration insight regarding the real current condition. The information could implies whether the organization is in safe condition or should be examined carefully due to the inability of its human resources to be able to adjust to the golas of the organization as general.

CONCLUSION
The research's result shows that affective commitment affect positively and significantly towards OCB; normative commitment affect positively and significantly towards OCB; and finally continuance commitment affect positively and significantly towards OCB. The later result shows a new phenomenon especially in hotel industry context at Makassar city, whereas due to the inavailability of vacancies in starred hotels, it leads to higher continuance commitment. This inavailability urges employees to show their better performance through positive behavior such as OCB.
Recommendation for further research are to perform empirical testing in the presence of mediating roles such as the role of organizational culture or local specific culture due to the unique diverse national culture from Indonesian (Thio and King, 2017); or specifically in organization level context such as counterproductive work behavior as a negative behavior that could inhibit the enhancement of OCB. For research in the context of hotel industry, it is recommended to conduct in another starred hotel contexts such as five-starred hotels or four-starred hotels which provide more specific employees' behavior to get a bigger picture and in order to be able to generalize the findings of empirical evidence in other studies.
