Journal article: We explore the consequences of the development of home working for wages, hours worked and employee health in the post COVID era. We base our research strategy on a French law passed in 2017 to encourage telework agreements between employers and employees. In the months following the law, many establishments signed telework agreements, and we show that this subsequently led to a much greater development of home working in these establishments after the epidemic shock in 2020. This increase was particularly significant in mid-level occupations, and was followed by a deterioration in the health of the employees concerned, particularly men.
