If you are doing a job that has already reached its ceiling I can understand. You have nothing to learn from other people. You get given a job and you finish it. Working from home has its many advantages but I do not envisage the office of Manchester United being like that. I imagine it a place where coming together and "banging heads" is far more beneficial. This isn't a workplace where you go from A to B. All day every day.
I think most would agree your views on WFH are misinformed, but anyway…
Man Utd is a large company like any other. The football side is one element, the rest will be normal business type stuff you’d find anywhere.
