I offered to support some colleagues with one of their responsibilities whilst a colleague was off a few years ago. This was an offer of temporary help and the responsibility is one that's time consuming and can be very stressful.
Every time I've raised that I'm still doing this extra responsibility to management I'm just basically told that I need to do it, despite my protests.
It's got the point now where me doing this extra thing is really affecting the output of my own responsibilities and I'm finding that I'm depressed, stressed and anxious on the days when I do this work. The job I used to love, I now dread.
Aibu to think they should now allow me to stop doing this extra responsibility? I'm sure that every time I mention or complain that I'm still doing this, one of the managers thinks I should just be quiet and get on with it and that I'm not a team player.
