Since the damage has already been done, there's not much worth "fighting" for now, except maybe clear your image, make them understand that they were wrong, apologize, bla bla bla. But narrow-minded people would never admit they're wrong. So, as thesecretfire pointed out, chances to win are slim.

As for retaliation, ethics, morals, reason, everything tells me " DONT !@#!@!#! " but my every gut says "go for it". heh. make the sys admins sweat for those $30/hr you paid 8-). Nevertheless, I'm not a roll model, and I strongly suggest you not to take any actions

the_g_nee: it's too late to ask for concrete proof, he already paid them and had his 5 days off (at least that's what I understood, correct me if i'm wrong).
