Companies and governments are experimenting with approaches like 4-day weeks or flexible holiday schedules. For the first approach, Iceland has published the results of a massive 4-day work week trial conducted between 2015 and 2017, which researchers describe as an “overwhelming success”. Further, a related study also showed working 1-day less per week reduces carbon emissions, mainly from reduced commuting. For the second approach to flexible holiday schedules, companies such as Mambu (a German start-up) is experimenting with giving employees Fridays off during the summer. Netflix and Deloitte are experimenting with unlimited leave policies, while other companies offer employees “special leave days” to celebrate a religious holiday or to spend a day volunteering.
