I do feel bad for this guy, because I feel that the majority of what he says is true, but it just can't be true that an employer saying he didn't work somewhere that he did is effective "blacklisting". I have worked a few places and received several job offers that I declined, and don't know of one case where my previous employer was contacted. I was told by HR at a fortune 200 company that I worked for as a mechanical engineer that they would not confirm or deny to anyone that I ever even worked there. I think that contacting previous employers doesn't happen much because so many people would lie. If the prospective employee was a charismatic fool, the previous employer could gloss over incompetence. If he was a great worker, but the previous employer was sore about him leaving, they could embellish on any shortcomings. Sir, if you are reading this, let go of the past and look inside for what needs to be fixed.
