Recently I've expirenced some bullying where I work. It started with a girl accusing me as the one who makes all of the mistakes and then it kept going from there. What's even more confusing is that now she is acting completely nice. I just wish there was something I could do to show bullies like her not to mess with me. I don't feel like I can trust her.
Are you still being bullied if so talk to your manager it's seems strange that she is being nice if it was me I would not trust her,.
But talk to someone in private or ask her why she is doing it.
Take care.
