(((((wanting)))))))

I've only had one job (that I kept for all of three weeks) but I'd suggest talking to the boss or the manager about what this supervisor said. As far as I can tell, if its not a breach of any confidentiality it is at least ignorant and rude of your supervisor to say anything like that.

*hugs* I hope things work out better for you with your new duties and you get things straightened out.
