Re: background checks?
Just because you sign a release saying that your prospective employer has the right to look at files from your previous employer doesn't mean that our previous employer will release them.
Another trend is that employers are hesitant to say anything about a former empllyee out of fear of being sued. Many former employers will only confirm that a person was, in fact an employee for a certain period of time. Most will also say whether or not you are eligible for re-hire. Many will say no more than that.
In your position, I would find out what the policy is of your former employer. If they will not release information about your previous termination, there is no reason to tell your future employers about it. If they WILL release that information, then it may be better to address it up-front, depending on the circumstances of that termination.
