BAuA-Working Time Survey (BAuA-WTS) is a micro data panel study covering aspects of working time, other working conditions, health, and well-being. It is representative of people working least 10 h per week in Germany. Data were collected via computer-assisted telephone interviews. So far, three panel waves have been conducted (2015, 2017, and 2019). Further biennial waves are planned. Scientific use files of the first two waves can be accessed at www.baua.de/forschungsdaten and be used free of charge by the scientific community after registration.
