Hello, not sure if this is appropriate to ask for opinions here?
I’ve had a conflict with my colleague at work, and I don’t know how to end it. I’ve recently been promoted to a managarial position, so some of my co-workers are my responsibility now. This colleague is a decade older than me, and she’s now not on my team, so technically I’m not her superior. Some time ago I needed a report from her, and I kept reminding her about it for weeks, and then I had to make her change it several times, because it was not up to our standards. We both know I was right the whole time, but she has a grudge on me, and my promotion has probaly pissed her off. She’s being ignoring me for weeks now, acting as if she doesn’t know me. I found out that she’s been gossiping about me behind my back, discusing my hair and my clothes. That’s irritating, but I don’t care about it. On top of that, she’s been telling people I’m aggressive and rude, apparently, because I was very streigthforward with her back than about her mistakes in that report. This makes me nervous. She is ruining my professional reputation. I don’t want other co-workers to have this wrong image of me, but I think I’ve noticed some of them being cold with me recently, for no reason.
Wha can I do to mitigate the effects of this gossip?
