OP here. I told my managers after two weeks that the trainee just was not getting it. They told me to give him time to pick it up. Tell higher ups every other day that trainee is not working out and finally told them I would not be helping him anymore. He is sinking fast. Don't think he will be around much longer. I have trained a number of people for this position and they all have had it figured out within a couple of days. I don't think it's my training.
