In India, the overall status of tea plantation workers and their working environment is governed by the Plantation Labour Act (PLA), 1951, and the rules framed by the state governments. Tea-processing workers are largely associated with ‘red-collar’ jobs that demand empirical study of their job satisfaction. Historically, tea-processing has been one of the major industrial sectors of Jalpaiguri district. This study determines the factors influencing job satisfaction among workers of tea-processing units in the Rajganj block of Jalpaiguri district. A semi-structured schedule was administered to 250 randomly selected respondents. Data were analysed using Exploratory Factor Analysis (EFA) followed by Structural Equation Modelling (SEM). Results show that wage and health-care facilities exert a strong positive effect on job satisfaction (β = 0.77). Welfare and job security (β = –0.04) and housing and supervision (β = –0.02) exhibit weak negative effects, indicating that moderate changes in these variables produce only slight changes in satisfaction. The findings underscore the primacy of wage and health-care benefits for improving job satisfaction in the tea-processing sector of the study area.
