Double check ALL your work. Just run through it again. Verify phone numbers, client or order numbers, return messages, follow through steps. It only takes a second and it will eliminate the next dreaded step in correction action. You will become known as a person who produces reliable work every time.
Check with the Boss. Stop in - don't be afraid - ask if she has a minute and just see if there has been any follow up. Exercise coolness and prudence in the workplace. Professionalism always pays off. Professionalism with a smile is even better.
