Comparison of occupational health problems of employees and self-employed individuals who work in different fields

We used a representative sample of the working population of Korea to compare the occupational health problems of employees and self-employed individuals who performed different types of work. The Korean Working Conditions Survey (KWCS) of 2014 was used to compare the working conditions and occupational safety and health (OSH) issues of employees and self-employed individuals performing different types of work. Relative to paid employees, self-employed individuals were older, more likely to perceive their health as bad, and had less education, longer working hours, more exposure to workplace ergonomic hazards, more musculoskeletal problems, and poorer mental well-being. Relative to those performing "mental work" or "emotional work", individuals performing "physical work" were more vulnerable to OSH problems. In conclusion, self-employed individuals in the sample were more vulnerable to OSH problems.
