Not only did he post it, but he posted his email, LinkedIn profile, and **stated** he was CFO of Vante. Thus, by his own actions, he linked his ranting to his employer. . . who let him go for conduct detrimental to the company. . .
He said he got back to the office and their voicemail was jammed to capacity (300 voicemails, all complaining about him.)
I would have loved to have been a fly on the wall to see the idiots face when he knew the jig was up.
