Was his demonstration helpful? Or do you mean that he was only able to do the tasks faster because he was rushing them, or that fast completion of these tasks was not really meaningful to the overall performance of the store?
Just want to make sure that it’s understood the point I’m making is that I had an obvious injury, still showed up for work, still did work, and was met with nothing but reprimand by this manager that I had just met. So in this particular case the benefit of a manager going down to the trenches seems only beneficial for one side.
