What should I do if I can't get an ex-manager's reference?

You are all very smart, so I figure you'd be able to help me.

I exited my previous job without giving notice (after a long period of harrasment). I wasn't there long enough to build any relationships with the other co-workers, and clearly the manager is looking for payback, so now I don't have any references.

I thought everything was alright with the job I had before that (good performer, long notice period, etc), but when I contacted my former manager to get a reference, he didn't return my call. Now I'm wondering if he is retaliating against me for leaving. I'm a bit shocked by this, but all the situation leaves me with are references from my co-workers at the "job I had before that."

Am I completely toast here, or is there something I can do?

Hopefully you have a reference to a coworker were you just left. It is better than no reference and will more than likely fillin the gaps in the story if someone calls. With that said, no one calls references these days. I have been listed for years as a reference and the few that do call me are just 'calling to check references' not usually interested in learning anything. The last guY that called had names confused and gave my name as the person applying for the job! Don't stress over it. Stay positive in the interview and good luck!
