Abstract:
Quality of Work Life in an organization is a critical factor for deciding organizational effectiveness and reducing the
negative behavior of workers. This concept is considered as a deciding factor of employee related outcomes. A
systematic study based on the hypothetical deductive method was carried out to glean empirical evidence from the Sri
Lanka Railways context, with regard to Organizational Commitment and its mediating effect on the Quality of Work
Life –Job Performance relationship. This study was correlational and cross-sectional in the time horizon and the unit
of analysis was the individual. A stratified random sample of 280 Station Masters was selected from the Railways
Department in Sri Lanka. A pre-tested, structured, self-administered questionnaire (utilizing a 5-point Likert scale)
was used to collect primary data. The SPSS version 23.0 was applied, and correlation and regression analyses were
conducted. Quality of Work life was positively and significantly related to Job Performance and Organizational
Commitment. Further, Organizational Commitment was positively and significantly related to Job Performance. The
construct of Organizational Commitment partially mediated the relationship between Quality of Work Life and Job
Performance. The results were consistent with the four formulated hypotheses, establishing that Organizational
Commitment mediates the relationship between Quality of Work Life and Job Performance of Station Masters who
work in the Railways Department in Sri Lanka. Hence, this study provides evidence to confirm the relationship
between quality of work life and job performance of the Station Masters working at the Railway in Sri Lankan context.
Further this relationship can be enhanced through the mediating effect of organizational commitment Theoretical and
managerial implications of the findings and directions for further research are discussed at the end of the paper.
