I took about 4 weeks off then I first broken my ankle, office based but constantly on my feet and in central London so having to negotiate central line at rush hour was not going to happen I also couldn’t work from home at the time and they were happy for me to take the time, so I did!
I was back at work after my op about 1.5 weeks later. I went back to work on a Friday as it would be quieter and meant I had the weekend to rest if it was too much (It was very open that the Friday was a test day really and if I felt I needed to leave half way through the day/take next week off that was fine) luckily it wasn’t and I was back in work but with shorter hours basically missing rush hour for a few weeks.
Can you not work from home? If they are happy for you to be taking the time off and not wanting to phase you back in then why not make the most of it!
