Part-timers forced to do unpaid overtime work

One-third of female, unmarried part-timers work overtime without compensation, a survey by a labor union federation showed Monday. The average amount of unpaid overtime worked by such employees came to some 10 hours a month, according to the Japanese Federation of Textile, Chemical, Food, Commercial, Service and General Workers' Unions.

The survey outcome indicates part-timers, most of whom work under the hourly wage system, engage in unpaid overtime as regular employees do, the federation officials said. The survey was conducted between February and April this year, and some 3,600 female part-time workers responded. Of the respondents, some 80% are in distribution and services industries.
