Please read further part of the  earlier story

Donkey started looking for job rotation. With a certificate of star performer and list of job responsibilities that he had handled, the new employer was thoroughly impressed; he decided to hire the donkey at double the salary of what he was getting earlier. Now the donkey was very happy as he got a good reward for his hard work.

Moral of the story: Work like a donkey (do all the work and take more responsibilities), if your boss won’t reward it, somebody else will.
