I had a chat last week with my boss and we talked about how I felt and what would make things better. She came to the conclusion that I was bored (maybe, maybe not).
Anyway, today we had a regroup with me, my colleague with the same title, and our manager.
She told my colleague that because I was "bored" we needed to shake up things.
There was a massive pushback from my colleague, to which I then explained that it was also to balance our workloads and our manager said that it was also so we were both exposed to different things.
Obviously I wasn't left with the best taste in my mouth, and think that maybe it could have been handled better? Maybe I'm overthinking it.
