My husband was offered to be a manager of others at his company 3 times. He would have been great. Each time he turned them down.

He knew you would have to do something unethical at some point. For instance, everyone works great, but you have only a few increases in pay you can give. And sometimes, someone has to take the low rating even though they're a good worker. He didn't want to sell his soul. For us, it was the best choice.
