Looking for advice before HR meeting, my employer (very big FTSE 500 company) asked me to take on an additional team with a very small payrise. Turns out this team needs extra managing, the role keeps expanding and they keep finding new projects for me to be involved in, so much so I didn't have enough time in the day to fulfil all tasks or duties they wanted, 6 months into this after speaking with my line managers they asked me to step away from my original team for 3 months to focus on the other team. Now it seems my original role has gone, no longer there/needed although the team have taken on some more work and haven't dropped anything from when I was overseeing.....it's being looked after now by my manager, just almagated into part of their duties. Now here's the thing, I absolutely hate the new team and tasks, its mind numbingly boring and nothing that I want to pursue as a career, not what was fed to me when they asked me to take this on. Am I within my rights to ask to step away from this and slip back into just my old role, there's been no formal "redundancy" of the role its just disappeared?
