The world-shaking COVID-19 triggered the rapid spread of telecommuting in Japan. The results of our survey on working hours have revealed that there are a variety of work styles, including cases in which workers come to work even on telecommuting days and cases in which they perform their work only from home. The purpose of this study is to conduct an online semi-structured interview survey of telecommuters and to use grounded theory techniques to extract the characteristics of the results.
