I'm so fed up with one of my colleagues being constantly negative about almost everything work related. It's been going on for about a year now - she's clearly not happy in her job.
We're a small team and I'm only in the office with her one or two days, but I dread them as find her mood/attitude ends up dragging me down. She doesn't even try and make an effort to hide her feelings to be more professional, or seem to have an awareness that her bad moods bring the rest of us down.
I've tried to be empathic and understanding, but it's not helped a bit and I've run out of patience. Not sure what my manager can really do about it though?
