Summary This survey was conducted as part of the Shorter Working Hours Promotion Month in November 2003, 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 31 years 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 survey investigates and analyzes in detail the current state of working hours, among other things, including taking days off on Saturdays, Sundays and public holidays and overtime work, against the background of strengthening administrative guidance for and growing public interest in the resolution of unpaid overtime, the accurate appreciation of working hours, and similar issues.
