We all are learn from getting constructive feedback. We learn what we're doing well. We learn what we need to improve.
Good managers provide constructive feedback to their employees on a routine basis. They give feedback when an employee does well to reinforce that behavior. Equally important, good managers give feedback when an employee needs to change what they are doing incorrectly.
Be sure that part of your day today, or sometime this week, you are spending time giving your employees constructive feedback.
