Summary This survey was conducted in order to gain a detailed understanding of the working hours, living conditions, and mental health awareness 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. Since 1972, this survey has shed light on the work environment in the construction industry for 37 years now, 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.

For this survey, the annual Questionnaire Survey for the Reduction of Working Hours was implemented in combination with the Living Conditions/Attitudes Survey conducted every three years, and the questions relating to mental health in particular were enhanced.
