I think I know the answer to this. So for about 3-4 years now I've worked at my place in central London which has a gym/swimming pool over the road. I go swimming 2-3 times a week in my lunch break which is lovely. I tend to eat lunch around 12, then go out 2.30-3pm and back by 3.30-4pm. Obviously you can't eat your lunch then nip out for a swim straight after
We had a couple of incidents in the last year or so, on a new project where execs needed my assistance and they couldn't get hold of me. So my boss has now said I can't go out that late, and I need to go somewhere between 12-2.30pm as that's a more acceptable lunch time.
To be honest, it's highly annoying. As I'm in central London the pool is much quieter after 2pm, all the times I've been at lunchtime/after work at peak times it's almost unbearable. To the point where after 3-4 years solid swimming I'm thinking it's probably not worth it.
So, man up and deal with it I guess? First world problems?
