While confessing an error can strike fear in the hearts of employees, those who value their work, their word and their future with your company will take responsibility and tell you the truth. Making errors may or may not cause great problems with a project or with your company, in general, but when an employee honestly and earnestly explains an oversight or mistake he has made, you have a better understanding of the issue and, even better, you understand that your employee values his integrity and your trust in him.
