I’m going to start this out by giving you a hypothetical situation.
There’s a guy who has only had one job his entire career and he was one of the best employees in the company. Even when his first contract was up, he decided he wanted to continue at that company to make the organization better.
Then a new, better employee came along and the guy didn’t complain. He thought it was great! The company could improve even more now. But that new employee is demanding and sometimes tough to work with.
The management at this company has never been great, but the guy figured he could just keep his head down and go to work and it would be fine.
