Summary This survey was conducted as part of the Shorter Working Hours Promotion Month in November 2007, 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 35 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 the relationship between long working hours and mental health problems, in order to approach working hours reduction from a mental health angle, as the long working hours that have become a regular occurrence are said to affect mental health, as well as physical health. In addition, it also investigates union members’ wishes about work styles, with a view to achieving work-life balance.
