You've recently hired a new employee. The employee performs exceptionally well and far above the level of your other employees. He's very friendly and behaves very professionally.
However, one morning the employee seems unbelievably pissed off. When you ask him what the matter is... he says its "none of your god damn business" and that you better "beat it."
You then tell him: "Choose your next words wisely, choose them true, and choose them right."
He then says to your face and in full view of the entire office:
"Okay then.
F*** the company.
**** this job.
**** you.
You can go **** yourself."
He then storms off and goes home, skipping more than half a day of work.
The next day he comes back to work, happy and productive as a clam. You have not yet talked to him about his behaviour that day but a few days later... he's back to his super productive and over-performing mode.
Assume that in the premise, your conduct towards the employee, including your words... are entirely appropriate according to the informal rules of the company. Please assume that this is a very typical, authoritarian, pro-employer setting and that management fully stands behind you because of personal ties.
So I ask you NSG...
What would you do about this employee? Would you talk to him (how and what about)? Would you fire him? Would you just let it go since it seems to be a one time incident?
