Hi, Marcia3dn, and welcome to Psych Central! I am sorry you are being bullied so. One possibility is that they are feeling threatened by you. Are you older than they are? Actually more educated or experienced?
However, that said, since this bullying is a pattern, it could be that you could use some advice about how to go into a new job and work so this bullying doesn't tend to occur. I suggest you begin to meet with a counselor and tell/him her about your past and current work events. Maybe something can be picked up on, and you can get advice about what to do or not do/say or not say to be seen as more of a team player and not a problem. Plus, it helps to have someone to talk to on a regular basis.
That's my thinking, anyway. Let's see what other folks have to say.
