Previous employer "phased me out" and at exit interview, I politely (truly was) shared with a senior exec my concerns about where the company's mission had been ignored. HR mgr told me at exit interview they would gladly rehire me if a job came open down the road. Just recently, I was given a verbal offer by a sales manager to rejoin the company, but the executive that was at the exit interview years ago negated the hire and told the sales manager he couldn't hire me. Is this potential blacklisting? Or breach of verbal contract by what HR mgr had told me, or breach of verbal contract since sales manager offered me the job? Can exit interview comments, especially non-confrontational ones, be used against a rehire in this fashion?
