I work for a municipal library in NJ. I started a job at a new library about 9 months ago. However, since we regularly meet with other staff from other libraries for training, meetings, or professional development, I frequently run into someone who was my supervisor at my previous job, with whom I didn't have a great relationship (hence why I left).
Frequently during these meetings, I'll find that they're talking over me or offering patronizing advice. I got particularly upset because I am actually the leader of a local organization, and this person very publicly contradicted and chastised me, and effectively tried to have me removed from my post.
When I sent them a private email expressing how I felt, they forwarded it to my current supervisor, encouraging them to discipline me for overstepping. They also cc'd several other people I work with, as well as members of my board, and while I don't think the content of my email was controversial, it was very embarrassing for all of these people to get dragged into it.
I'm not sure what to do because this person has refused to show me respect as a peer, and if I try to hold my ground, they just try to have me punished.
Has anyone else experienced anything like this?
