A research study recently reported in the Harvard Business Review found that the vast majority of employees are quite excited when they start a new job. This study also found that in 85 percent of the companies surveyed, this excitement declines sharply after the first six months and continues to decline for years afterward. One of the big reasons is that their managers didn’t take the time to thank them for a job well done, yet these same managers were quick to criticize them for their mistakes. What these managers fail to realize is that if they would focus their efforts on showing sincere appreciation to their employees instead of pointing out mistakes, their employees would make far fewer mistakes. Saying “thank you” often not only energizes your employees, it makes you a more effective manager.
