I have a job on my resume. I left it due to problems with one of my managers. I had no problems with anybody else there (including the other managers), and I am sure if any of these other managers were contacted for a background check and review of my performance, they would not be out to make me look bad.
However, I can't say the same for this one manager that I had an altercation with. So how do I avoid my next company getting in contact with this one guy?
In particular, I am wondering how a company performs a background check. Do they
Just call up HR and talk to them to verify info? Is HR even allowed to give away such info?
Call up HR, and then HR gets them in contact with some appropriate manager under who I worked?
Ask me personally for a contact person at the company?
If it is 3), then that's great, I can just provide them the contact number of some of other managers. If it is 2), then I guess it is out of my hands?
