That's exactly what is playing our before our eyes. And, believe me, it does happen in business quite regularly. And what happens in business is the idiot angry bosses alienate the employee further and give him the courage of his convictions. And the other employees watch what's happening and think "I wouldn't want that to happen to me. This place isn't what it's cracked up to be".
It's ridiculous, short-sighted, old school management.
20 years ago I resigned from a job was doing well i because I preferred the other company and the career they could offer me. When I resigned they gave me "garden leave" but insisted I come into the office the next day. When I did, they locked me in a room with a big list of companies for me to "cold call". Now this sort of stuff was not what i was paid to do, and I had no incentive whatsoever to get any results, so i sat for half a day tossing it off. All day employees were sneaking in for a chat, and expressing their disgust that they were effectively punishing me. After lunch I called in my direct manager and said "This is no good for you, it is no good for me, it's a waste of everyone's time, and it's distracting your staff". He went away, spoke to his boss and then let me go. I soon moved into management in my new company and went back and recruited half of their staff.
So the peevish idiot boss had succeeded in pissing me off enough to feel no regret about going back to pinch his staff, and had given the message to his staff that he was a twat, contributing to them ultimately leaving.
Abu Dhabi know the score. Act honorably. Treat people fairly and you will get the rewards.
