Leadership mistake #2: Ignorance

Many supervisors focus only on outstanding performance. The broad segment of average (and thus still good) performance is ignored and taken for granted. For employees who form the backbone of the team with solid and average performance, this behavior is very demotivating. 

How to do it better: Make sure that ALL work results are regularly appreciated. Even in a work result that you are not satisfied with, there is work and heart and soul from the team. In practice, a simple "thank you" works wonders.
