Flexibllity is the key. Let the teams decide how they work best. Mandates, one way or the other, are silly.
I think that's where it breaks down and the people in the office get the worst of both worlds. It's actually less constructive to be in an office where you are taking calls all day with multiple remote employees that could be in the office. I don't go into the office at all anymore, but I would be happy and happier to be back in the office 3 days a week if I knew the teams I worked with were also in the office. Pre pandemic I had a very flexible in office policy where the norm was to be in the office 3 or 4 days a week. But folks that had long commutes were able to leave the office early and work from their commuter trains to wrap up the day. Folks on the team would roll in anytime between 830 and 11am. I think the unfortunate thing about RTO policy is that coming down from HR in a 1 size fits all approach makes it less flexible and terrible with badge swipe counting and what not. And in order to be fair, some type of written policy must be in place, but teams, managers, etc. should have flexibility to make it work for their teams.
