"The most frequent complaint of all individuals about their jobs is that they rarely are told when they are performing well. Except for the annual performance-appraisal ritual, performance is discussed only when problems arise.
"Making recognition a formal part of the system reminds managers that reinforcing good performance is just as important as confronting poor performance. It also makes employees aware of the organization's expectations that they will be recognized when they perform well." (Discipline Without Punishment. By: Grote, Dick, Across the Board, 01471554, Sep/Oct2001, Vol. 38, Issue 5)
I believe this principle applies to our personal lives as well as on the job. When did you last take time to complement someone in your family or in your workplace for a job well done?
