When Scott Yaremchuk picked up a magazine article on how to manage health care workers, he was pleased to find some advice.

Scott was concerned about poor or mediocre performance on the part of several physiotherapists in his clinic. The author of the article said that the “best way to improve performance is to make your workers happy.” Scott was glad to have read this article and made a pledge to himself to start doing a much better job of making his employees happy. But should Scott follow this advice? What do we know about the relationship between job satisfaction and performance, and to apply this knowledge to the performance problems Scott has observed at his clinic?
