Abstract:
This paper is a systematic study based on the hypothetical deductive method carried out to glean empirical
evidence with regard to organizational commitment and its mediating effect on the relationship between
the quality of work life and job performance. 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 was used to collect primary data. Correlation and regression analyses were conducted to
test mediation. The results were consistent with the formulated hypotheses, establishing that
organizational commitment successfully mediated the relationship between quality of work life and job
performance of Station Masters who work in the Railways Department in Sri Lanka. Implications for theory
and practice have been discussed.
