I have a team split between 5 cities and timezones using modern software development work practices. I offered to comply with my employer's 2 day in-office mandate, but made it clear that on in-office days I wasn't going to work extra hours to support my teammates who were offshore. I was given an exemption.

My team does 0 days in and 5 days WFH and it works really poorly. Terrible communication and extreme siloization.
