Oh boy I was there two months ago. I had the PERFECT job interview. They were agreeing to my salary requirements and all. They told me they'd have to contact my ex-boss (the man who harassed me daily for a year straight) after I told them it was not a good parting. All of the sudden they gave me an EMAIL telling me that they wanted an employee that was willing to come into the office 5 days a week instead of the 2-3 I offered. I emailed them back and said I'd be willing to do the 5 days in the office, but felt I'd be more productive away from the office for a few days a week (which is totally true because at home I get NO interruptions and distractions) and never heard back from them again. I KNOW my ex-jerk-boss spoke badly of me. I KNOW its illegal, but how to proove it?

Is it possible the ex-boss is not returning their calls and they can't do anyting about it? Did you say that you're still friends with other employees there? Could you have them call the new place and offer a referal for you? If its a vet giving the referal, that has to carry some weight, even if it wasn't the main vet.
