Effort-Reward Imbalance and its Association with Health among Pluckers in a Tea Plantation in South India.

Context: Work-related stress is associated with cardiovascular diseases, musculoskeletal disorders, psychological ailments, and work-related injuries. Imbalance between high effort and low reward at work can lead to work stress among plantation workers.

Aims: To assess the effort-reward imbalance (ERI) among pluckers in tea plantations in South India and its association on chronic health problems, substance abuses, and workplace injuries.

Settings and Design: A cross-sectional study was conducted among 346 tea pluckers from May to June 2015 in six selected tea plantations in Anamalai, South India.

Patients and Methods: A short version of ERI questionnaire was used to assess the work-related stress among them. Along with ERI questionnaire, sociodemographic details, chronic diseases, substance abuses, and workplace injuries were ascertained.

Statistical Analysis Used: Sociodemographic variables were described as frequency and measures of central tendency. Tests of association, such as Chi-square test, were applied.

Results: Among the study population, 322 (93.1%) reported more effort, 23 (6.6%) reported more reward, and one (0.3%) had no imbalance between effort and reward. Those in older age group (≥51 years) experienced more effort compared to those in younger age group (≤50 years) (Fisher's exact = 21.905, P = 0.001). Educational status (Fisher's exact = 15.639, P = 0.027) and work experience (Fisher's exact = 23.122, P = 0.003) increased the effort rather than increasing the reward associated with work. No significant association was found between ERI and any chronic diseases, substance abuses, or injuries.

Conclusions: Majority of pluckers in tea plantation experienced more effort compared to reward.
