This guide helps managers determine which of their problem employees may need a little encouragement, a little direction, a full-fledged attitude adjustment, or to be set free. Managers learn how to work with a myriad of challenging personality types-from those who just can't seem to get the job done to negative, whiny, and uncooperative ones. Employers learn the importance of setting goals, observing and assessing performance, and responding with motivating and nonnegotiable performance standards.
