I work in manufacturing. When co-workers join me to help lighten my load, I find it very hard when they don't follow instructions and make potentially defective units. I make hundreds of units a week, and have learned some ways to avoid certain defects.
I don't know if my problem is communication: diplomatically showing people the best way to do things.
Or, if it's perfectionism: "who cares, let your coworkers learn from their own mistakes, that's the best teacher".
I worry about our customers having future problems, or later departments having to send things back for rework.
I listen to Epictetus and Aurelius, but when the moment actually comes up in real life it's hard to apply the lessons. I think about Epictetus' quote, something along the lines of "maybe your slave spills a little oil, that is the price of peace of mind". Sometimes my coworkers get angry at being told what to do, I think about Aurelius highlighting the different people we will deal today with and how we should accept them.
