Junior team members, the ones that are supposedly most eager to come to the office, are working from home more than the allowed maximum.
Ha, I've seen the same thing. I have two junior-ish reports, and when we started the discussion of eventual return to office last year they both said they would be in all the time to soak up the team building and culture establishment they missed out on. We returned to voluntary office work for those that wanted it three months ago and neither one has made it in a single day, they have stayed full remote (and they get their work done so I couldn't care less.)
