I don't, however I am generally able to flex my days a lot due to working mostly from home and also being able to complete my work fairly quickly.

A lot of people at my employer do work different schedules though. Either 4 day weeks or compressed hours (9 longer days & one day off).

I think it's a cultural thing where the organisation recognises work is work and you also deserve a life on your terms.

All of us seem pretty happy with our setups...
