Honestly, we don't have the full context.

As I've stated previously here, I'm no fan of Mr. Calacanis, but there may be a whole host of legitimate business reasons why he wishes to no longer have this employee on-site.

Whatever the full context, it's VERY unprofessional (also likely violating his MCA or NDA) of this employee to post what is clearly proprietary HR-related information to the public Web.

I'd say these bridges aren't just burned, but well and surely nuked.
