Summary This survey was conducted as part of the Shorter Working Hours Promotion Month in November 2008, in order to gain a detailed understanding of the working realities and attitudes of members of unions affiliated with the Council of Japan Construction Industry Employees’ Unions (JCU), feeding the findings back into initiatives related to shorter working hours conducted by JCU and its member unions, and thereby contributing to improvements in working conditions across the board.

In November every year, JCU conducts a survey with approximately 25% of union members (approximately 10,000 people) to gather information on their working hours. For 36 years now since 1972, this survey has shed light on the work environment in the construction industry while adapting the content of the questions to suit changes in society. This is the most extensive and consistent survey on white-collar workers in the construction industry.

In this survey, the normalization of long working hours among workers in the construction industry is examined in separate occupational groups, yielding analysis of the attractiveness of the industry in connection with work and life satisfaction and working hours.
