Summary Against the backdrop of continued efforts at shorter work hours, new forms of work hours such as flextime and discretional hours have been introduced to the workplace in accordance with the reconsideration of personnel and labor management, diversified forms of employment, and changing worker consciousness. All this, in general, is considered to help reduce work hours, but is also affecting corporate control of employment and work hours as well as workers' morality and consciousness. This survey was conducted to provide basic data for promoting shorter work hours and workers' welfare by investigating the actual state of work hours, effects and problems of the new systems, and issues of shorter work hours and union efforts to be tackled in the future.
