The eager beaver

James is a new employee at an insurance company. He is an eager beaver, but after a while his colleagues began to complain about him, asking "What does he want, a promotion? " Then another colleague said, "He makes me look like I'm slacking."
One day, James was called into the office of the personnel manager. The manager said, " l'm sorry that l have to tell you bad news. You can't continue to work here.
James said, "Because my colleagues thought that l'll be taking their jobs? l won't."
The manager said, "No. If l let you stay at this company, maybe you'll be taking my job! "
