Abstract
Background and Aim: In high-risk operational environments such as oilfields, physical and psychological factors can undermine employee productivity and positive organizational behaviors. This study aimed to examine the effect of ergonomic skills training on enhancing Organizational Citizenship Behavior and productivity among operational staff of the Azar oilfield.
Methods: This quasi-experimental study employed a pre-test–post-test design with a control group and was conducted on 40 male operational workers. Participants were randomly assigned to either an ergonomic training group or a control group (20 participants each). Data were collected using the OCB questionnaire by Podsakoff et al. (1990) and the HPQ questionnaire by Hersey and Goldsmith (1980). Analyses included independent t-tests, analysis of covariance (ANCOVA), and within-group comparisons.
Results: After the 4-week intervention, the ergonomic training group showed significant increases in total OCB scores (from 105.6 to 118.4; +12.1%) and HPQ scores (from 128.8 to 145.6; +13.0%) (p < 0.001). The greatest OCB improvements were observed in altruism (+15.3%) and conscientiousness (+14.8%), while HPQ improvements were highest in motivation (+16.2%) and ability (+15.4%). Cohen’s d effect sizes ranged from 1.78 to 2.20, indicating a high level of effectiveness. No significant changes were observed in the control group (p > 0.05).
Conclusion: Ergonomic skills training markedly improved organizational citizenship behavior and productivity among employees of the Azar oilfield. These findings underscore the strategic value of investing in ergonomic training programs to enhance both individual and organizational performance in high-risk workplaces.
