Depends on the team and the job, which is what I appreciated about this employee's question. He brought up that for his team, there were 7 people scattered around the globe. RTO didn't make sense for them.
I manage two teams with 10 direct reports total. 9 of them are in NYC. Having some days in office absolutely has benefits. Personally, mandating 5 days in office doesn't make sense to me. People come in 3 or 4 days and that's great.
There isn't zero evidence that working in person has benefits. That's silly.
