I quite like WFH, but have mixed feelings and miss work friends, so if we have a blend of WFH and office 50/50, that would be the perfect compromise for me. Could be that we're all split into two teams, and Team 1 go in 50% and TEam 2 the other half of the time - either half the week each, or on different weeks.
I don't miss getting up earlier, commuting, rushing to get ready, as well as checking the teenagers have everything. Much prefer making lunch at lunchtime and having more varied lunches at home. It's also handy to be able to pop to local shops - butcher, baker, greengrocer, that are only open till 5pm (not a fan of spending all food budget with supermarkets).
I do miss work friends from the old teams, as I changed jobs in Feb, so although the new team are lovely, I haven't known them for long and miss bumping into people, although I keep in touch privately with a couple of people.
I'm concerned about the uni toilets, as many are in public areas and accessible to anyone, and there will be queues as one person will be allowed in at a time. I wish they would convert the cubicle ones to separate enclosed room toilets with washbasin, like disabled toilets, but that would be £££.
