I bet when you first read the title you thought it was over the top. This is from a company we worked with years ago that had less than 15 people when I first started working with them. I'll never forget the day this conversation took place. It still reminds me of the value of teaching coaching and what I do for a living.
A manager of one of our clients sites was extremely upset with one of his employees. He was in the "lobby", but due to the small size of the company, everyone could hear what was being said. The manager got in the employee's face, began to yell, literally called the employee stupid and began to use profanity. In the spirit of time I'll cut to the end of the story. The employee was extremely upset and abruptly left the company quitting without a two-week notice.
