I'm not even a fan of ghosting in the dating world, and I can't even fathom how unprofessional you have to be to do it in the workplace. But, because a lot of people simply can't stand confrontation, it happens more often than it should.

As is often the case, the best revenge is served cold, and this dude bided his time and waited to exact his vengeance when it would hurt his former employers the most.
