Who do you use as references?

[~Shrek~]

In school, my professors were willing to write recommendation letters and act as references. I have one former supervisor that was willing to be a reference over a year ago, but she moved jobs. My other former supervisor told me she is not allowed to act as a reference per HR policy.

I don't know who I would ask. I am nervous asking current coworkers. One coworker encouraged me to apply for an open position, but when I asked her if she was willing to be a reference, her reply was not very enthusiastic (but a yes).

Was it taboo to ask a current coworker? I don't really know who I would ask. I don't feel comfortable letting my boss know nor do I feel comfortable talking with other coworkers. My old professors may be willing but the time I have been out of school gets longer and I hope that they still remember me.

I think it is ok to bump
