Discussion

We conducted an empirical study aimed at exploring the relationship between employee satisfaction, job involvement, organizational commitment, work characteristics and organizational policies and procedures.

Based on the relevant scientific literature, recent studies in the area and the integrative model of work motivation of Locke and Latham, we have formulated an initial conceptual model for our research and hypothesized the connections between the relevant variables. The initial model has been improved iteratively, with the goal of increasing its fit to the empirical data collected in the study.

Starting from the model proposed by Locke and Latham we determined that their model does not fit our experimental data well and that we observe a connection between job involvement that is not present in their model. In addition, our data does not support the hypothesis that organizational procedures and policies affect employee satisfaction in the organizations considered. As a result we propose a 4 factor model shown in Figure 4C for the relationship between the concepts of work characteristics, employee satisfaction, job involvement and organizational commitment.

We analyzed the results of the study based on 1 general and 5 specific hypotheses. The research confirms that there is a link between work characteristics and job satisfaction (H1), but that it is weak, suggesting that a dominant effect of the material factors of motivation exists.

We have also determined that there is a connection between the rules and procedures variable (H2) and the rest of the variables, indicating that it should be considered in future studies, but that the constructs need to be operationalized better.

The third specific hypothesis (H3) that job satisfaction has a positive relationship with job involvement has been confirmed and we have observed that extrinsic work motivation has a stronger effect than intrinsic, which can be explained by low wages and insufficient funds for everyday life. Other research has confirmed this link and showed that most of the employee motivation dimensions have significant links with the dimensions of job involvement (9 out of 10 pairs).

The fourth specific hypothesis (H4 - Job satisfaction will have a positive relationship with organizational commitment) has also been confirmed and we can conclude that a positive relationship exists, which is in line with recent research in this area. The subscale focused on identification with the organization is strongly connected with both intrinsic and extrinsic factors of job satisfaction, but this cannot be said for the subscale focused on organizational attachment. Our research supports the existence of a weak connection between job satisfaction and organizational attachment, both when intrinsic and extrinsic satisfaction is considered as a motivator. A study of work motivation and organizational commitment conducted in Bulgaria (Serbia's neighbor) showed that extrinsic factors are key sources of organizational commitment, as well as that job involvement and the chances for the fulfillment o higher-order needs pay a very important part in the motivation of the employees.

One of the reasons for such a result can be the economic situation in Serbia, which has a severely detrimental effect on work motivation. The transition and economic crisis is accompanied by the shrinking purchasing power of the population, higher unemployment rates and a rising disparity in the salary levels, all of which causes the adjustment of the behavior of the employees to these conditions. Under the economic conditions that exist in Serbia it is to be expected that the individuals will put more value on the salary and advancement prospects than on the opportunities for growth and development, which do not present a direct financial benefit.

The research did not reveal any differences with respect to the sex of the participants, regardless of the variable considered. Other research has not reached a consensus on the matter, as a part of the studies suggests that there are differences in job involvement between men and women.

Regarding the ownership of the organizations examined, the research revealed statistically significant differences between the employees working in public and private companies, i.e., that the participants working in the private sector scores significantly higher on every variable except work characteristics, meaning that they are more committed to work, more involved and more satisfied.

In addition, we have determined that there are statistically significant differences when it comes to the position of the employees in the organization's hierarchy, i.e., whether they occupy a managerial or a non-managerial position. The study shows that managers have higher scores for organizational attachment, organizational commitment, intrinsic motivators, extrinsic motivators, job satisfaction and job involvement. We can, therefore, conclude that the managers are more satisfied with their work in general and that they are more committed to the organization than other employees. This can be explained by the fact that, due to the nature of the work they do, they are able to make decisions, they have a more varied job and have better material and non-material rewards. A more detailed analysis of the commitment of the managers, focused on identifying if we are dealing with normative, continuous or affective commitment would provide more insight into the structure and nature of the relationship between the organization and the individual.

Considering the type of the company (manufacturing or service) our study showed that the participants working in manufacturing companies are the ones who identify more with the company, are more committed to the company, more satisfied with their work and more involved.

Our study also identified a significant difference with respect to the vocation of the participants, showing that those with training in humanistic sciences awarded most positive scores to the characteristics of their work, while the opposite was true for those of technical vocations.

The part of our analysis focused on the age of the participants revealed that there is a statistically significant connection between the age and job satisfaction, where the older the employee, the less satisfied he/she is with their job and cares less about the characteristics of work. A reason for such a result could again be found in the economic situation of Serbia and the high unemployment rate (over 20%), causing the younger people to be satisfied with the simple fact that they managed to get a job, rather than being satisfied with the job itself. Another reason could be the difference in the perception of desires and possibilities that exists between the younger and older employees.

The years with the company are negatively linked with employee satisfaction, as well as job characteristics, which is in line with the effect discussed in the previous paragraph, as those with more time spent in the company are less satisfied with their job and care less about the characteristics of their work.

Considering the level of education of the participants, our study showed that the more educated the employees are, the less involved they are in their work and that they seem to care more about the characteristics of their work.

Our research showed that links exist between all the variables studied and that the weakest of these links is between work characteristics and other constructs. Of those, the weakest link in turn is the link between the work characteristics and the subscale of organizational commitment related to the identification with the organization. Thus, we can conclude that work characteristics do not exhibit a significant influence on whether and to what extent the employee will identify with the organization in which he/she works, i.e., whether he/she will be committed to the organization.

A moderate to strong connection exists between organizational commitment and job satisfaction, which is in line with the results of numerous previous studies

Our study confirms the existence of a strong connection between job satisfaction and job involvement. Many studies have been carried out in an attempt to examine and define the relationship between job involvement and organizational commitment. Our results are in line with previous studies, which diverge only on the strength of the connection, ranging from moderate to strong. Our study provides more evidence for the existence of such a relationship, which is moderately strong. Such a relationship does not exist in the integrative model of Locke and Latham, which served as a starting point for this study.

In addition, we have determined that job involvement has a mediating role between job satisfaction and organizational commitment. Job involvement mediates the influence of satisfaction on organizational commitment, but this is a partial mediation and a major part of the effect of satisfaction on the organizational commitment is achieved directly.

The construct related to organizational policies and procedures seems not to have significant bearing on employee satisfaction, based on the data collected. Two plausible explanations exist for this. The first is the fact that this was the only construct in our study for which a suitable standard questionnaire could not be found, so one had to be constructed specifically, meaning that the construct should be operationalized better in future studies and that this represents the limitation of our study. The other is the fact that in Serbia, as in most transition economies, the lack of suitable institutional and legislative framework at the national level is often accompanied with lax, not clearly defined and even less adhered-to business policies and procedures. In such a state of affairs, the employees seldom have a relatively clear idea of what the policies and procedures of their organization are and are unable to evaluate them with respect to those of other organizations, making this construct very hard to measure. At the same time it can be argued that, in such a situation, the policies and procedures are not perceived by the employees as a significant factor of their organizational behavior and indeed do not affect their work motivation. Whatever the reason, the relationship of policies and procedures to the other variables of work motivation within the transition economies merits further investigation.
