Abstract PDF: Although South Korea's average annual working hours have declined over recent decades, the country continues to rank higher among Organisation for Economic Co-operation and Development countries. Despite ongoing policy debates on working time reform, public perspectives on specific regulatory measures among Korean workers remain underexplored. This study analyzed data from the 5th wave of the Korean Work, Sleep, and Health Study (KWSHS). The survey was conducted in September 2024 via an online platform. A total of 5,783 working adults aged 19–70 years were included. Participants were asked about their opinions on five working time regulatory measures, including the current weekly hour cap, extending regulations to small companies and exempt industries, introducing a daily working hours limit, regulating non-essential night work, and restricting weekend work for large supermarkets. A majority of respondents supported all five proposed regulatory measures. Support was highest for introducing a daily working hours cap (72.1% agree or strongly agree), followed by regulating non-essential night work (63.2%), extending the cap to small companies (60.1%), restricting weekend work for large supermarkets (60.7%), and introducing the weekly cap for exempt industries (52.8%). While 34.7% favored reducing the current weekly maximum, 36.5% preferred maintaining the current limit. The survey respondents generally support strengthening working-time regulations. These findings provide workers’ opinions on working-time regulations, although they should be interpreted within the study's limitations (a sample with a higher proportion of office workers).
