Don't let frustration, anger and rage cloud your judgment when making decisions.
Just before New Years, I got a call from a contractor. He was very upset. One of his employees was griping to all the other staff members in the parking lot about how small his Christmas bonus was. He felt he deserved more and was letting everyone else know about it. The contractor saw him sulking around the shop and pulled him into his office to ask what's up. When the employee admitted to bad feelings about the size of his bonus, the conversation got ugly and they both left the meeting angry.
The owner was upset because the employee had no appreciation of what it cost the company to give the annual Christmas bonus no matter how well the company did that year. The employee was upset because he felt he didn't get a big enough bonus and now he was getting beat up for telling his boss who asked what he was upset about. It was a lose-lose situation for everyone.
