Summary This survey is conducted in November every year with approximately 10,000 union members to accurately understand the prevailing situation of the members of the Council of Japan Construction Industry Employees’ Unions (JCU) in terms of working hours, living conditions, and their general perceptions of work and life. By feeding the results back to activities toward the reduction of working hours as promoted by the JCU and its affiliated unions, it aims to contribute to improving the overall working conditions.

Since 1972, this survey has shed light on the work environment in the construction industry for over 40 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.

In this survey, in order to gather insight into union members’ lifestyles and household finances, we have added questions on their lifestyles and sensibilities. We have also added questions regarding their awareness of the possibilities to be transferred abroad (which are thought to increase in the coming years).
