Bad-mouthing the boss via email
You’ve probably had your moments where you want nothing more than to choke your boss. Many of us have been there, but many of us don’t act out on these fantasies. At most, we badmouth our bosses behind their back with coworkers who feel the same way. This person accidentally took it a step further.
After receiving some pretty unintelligible instructions from their boss, this guy sent out a pretty hurtful email to his coworkers. He didn’t realize that he CC’d the email to his boss until after he hit the send button. This was before you had 30 seconds to retract your email, so the guy was doomed.
