What you should do if you make a mistake at work. Mistakes at work can happen to anyone and even serve for personal development.
A positive error culture serves experience and helps to develop new solutions and make learning progress. Simply ignoring the mistake could increase the difficulties and, in serious cases, even lead to immediate termination and leave you with a persistent bad conscience. If you want your life and job to always go according to plan, you should write your own obituary and try to live up to it or act accordingly.
