So colleague is senior to me but we also have the same manager.
My manager and I have an agreement that I can log out of my phone 3-4pm. Our job isn’t particularly call based and you get like 3 a day max. Due to anxiety I’m allowed this break a day.
Today my manger was off and the senior told me to log in, he said he was aware of the agreement but one time wouldn’t hurt would it?
I think if discussed beforehand then I would have done it but springing it on me with 10 minutes to go I think is very unfair. There were other people logged into their phone so they weren’t left with no one answering calls.
