The thing is, our office work policy comes from our team, not management. In fact, our company policy is 3 days in office, but we, as a team, decided we're less productive with that policy (we tried it for a month) and our VP overrode company policy for us.

Some people come in every day, some work full remote (due to extenuating circumstances), but most come in 2 days/week. If we're sick, need to be home (e.g. having a handyman come fix stuff), or need to be out of town for an extended time, we stay home. In fact, one coworker has been full remote for a few months because her dog is prone to having seizures and she needs to be present to help reduce harm until she can find a treatment that helps. It's a non-issue.

The expectation is just that, as much as possible, come in on the two days the team has agreed on so collaboration can happen. Most of the team does that most of the time, and when we can't, we just leave a note. Likewise, if we need to go to an appointment, leave a note that you'll be out for an hour or two and take care of it.

It's a super flexible and bottom-up policy, and it works really well. The important thing is that it's a team decision. I think it has resulted in us liking spending time together, so we periodically do team activities outside of work (funded by the company of course), and nobody is obligated to attend (but most do).
