If an employee performance is down, do the following:

“Bill,” he said, “you are a fine mechanic. You have been in this line of work for a good number of years. You have repaired many vehicles to the customers’ satisfaction. In fact, we’ve had a number of compliments about the good work you have done. Yet, of late, the time you take to complete each job has been increasing and your work havs not been up to your own old standards. Because you have been such an outstanding mechanic in the past, I felt sure you would want to know that I am not happy with this situation, and perhaps jointly we could find some way to correct the problem.”

Bill responded that he hadn’t realized he had been falling down in his duties and assured his boss that the work he was getting was not out of his range of expertise and he would try to improve in the future.

Did he do it? You can be sure he did. He once again became a fast and thorough mechanic. With that reputation Mr. Henke had given him to live up to, how could he do anything but turn out work comparable to that which he had done in the past.
