I would have done, but I soon realised my manager and this co-worker are thick as thieves, very gossipy with each other, I'd come into work, and they would stop talking, so I felt that they were talking negatively about me - my manager acted worse around me when that co-worker was around, and nicer when she wasn't

I feel that this co-worker had more power than my manager, I felt sometimes, that my manager wanted my co-worker's approval, not the other way round
