My post-vaccine plan is to have a "mulmen day" where I set the expectation with my teammates and stakeholders that I am in the office and a "float" day where I come in to align with someone else's day who I need to work with face-to-face for whatever reason. If everyone works this way then we can meet most scheduling needs. If we expand this to two float days a week then it is trivial.
There's no reason for the whole team to be colocated on the same day on a regular basis. Those kind of team-wide meetings never benefit from whiteboarding or any other in-person process. In fact the limitations of remote work make that kind of collaboration better because you have to actually prepare your thoughts and material.
Even pre-covid getting calendar time required a week of notice. Office hours were once-a-week and required at least 24 hours notice. Personally my office hours are on Wednesday. If someone books a session I come in, if not I don't. Nothing changes.
In Covid times I have had the most productive period of my career while my team grew by 50%. I have no problem getting coworker time ad-hoc, even remote. Communication is not difficult. We got better at using tooling to write documents and draw diagrams. We don't use whiteboard analogies.
I honestly see no downside to the remote work and a long list of personal, professional and environmental benefits.
If it's all the same days that'd be great but doesn't seem like it's work for everyone. I know certain days/times where I can't have meetings at home because the space is otherwise occupied and I need to keep quiet etc.
Maybe also by waiting to start the meeting we're enabling it all too?
I find it all too much to keep track of, so perhaps simplifying it to "meeting starts at X, be there or be square" is all that's needed and behaviour will adjust accordingly?
Food for thought.
I've seen some comments that WFH and it's variations (full remote vs partial) are a skill like anything else and need to be developed. I'm not strictly speaking a fan of it all really, but that's just me, and I think the "more productive vs less productive" debate is actually a ruse and that the real argument we're all getting into is "this makes me feel better vs this makes me feel worse" which you simply can't logic your way out of, so I get that it truly does suit some people.
I think I just need to take the mindset that it's a skill I need to develop a little further and some of my gripes with it will ease or melt away.
Seems like, at least in my neck of the woods, 2 days WFH is becoming a standard benefit touted by companies to attract candidates now.
