I used to work at a job where we apply labels to wires and plug them into connectors.
One particular job they said that they were getting a lot of problems with people doing them incorrectly so they were very particular on how the labels were applied. At first the only thing I questioned them on was that for some reason they wanted us to apply one label on each of the cables then go through the work again and apply the other two even though it really didn't make much of a difference.
The big problem was that they had us very specifically orientate the labels and a specific way because they were 'twisting' as the labels were applied, order of them being done one then two made no difference.
After doing almost 300 of them the leads came back and said that they were done wrong and that they were twisted. My partner and I were doing them exactly as directed and they were coming back wrong.
I pointed out with the way that we were directed to do them, they would of course turn out wrong. They tried to cite that I was just not doing them in the order that they wanted which both of us did regardless.
And after 2 days of animosity my partner and I woke up to being fired.
