I was taught that my job is "to make sure all my bosses surprises are pleasant ones". 15 years of working as an engineer and that never changed. Now I have my own business and that's the thing I look for employees.. someone I can leave on their own to do a job. It they have problems they can always ask me. If they screw up I expect them to tell me immediately and to have a plan of action to fix it and to prevent it happening again. And I never ever get cross if someone does come to me and say they screwed up. Far better that we tell the client about a problem than wait until the client finds the problem themselves.

Reading all these comments makes me realize how lucky I've been in my career. I've always had great bosses who defended me and backed me up.
