Food Manufacturing Workers and Structural Causality among Work Environment, Work-Family Conflict, Musculoskeletal Pain, Sleep-Related Problems, and Burnout

This study analyzes the association and structural causality among work environment, work-family conflict, musculoskeletal pain, sleep-related problems, and burnout in the food manufacturing industry. This study used the 6th Korean Working Environment Survey data, and 523 food production workers were selected as research subjects. Structural equation modeling showed that work environment and work-family conflict significantly affected musculoskeletal pain. In addition, work-family conflict and musculoskeletal pain affected sleep-related problems, and musculoskeletal pain and sleep-related problems impacted burnout. Furthermore, this research provides practical strategies to deal with musculoskeletal pain, sleep-related issues, and burnout. Burnout is more affected by sleep-related problems than by musculoskeletal pain. Additionally, sleep-related problems seem to be more affected by musculoskeletal pain than by work-family conflict. Meanwhile, musculoskeletal pain is influenced by the work environment rather than by work-family conflict. This result can be used to establish preventive policies for the safety and health of food manufacturing production workers.
