Niggers basically read the first 5 letters of a word and move on to the next. They are illiterate. If an HMI has buttons reorganized someone has to show them what buttons need pressed in what order. It doesn't matter if an error message pops up telling them the button doesn't do anything, if that's how they learned it, it becomes a voodoo ritual and it's getting pressed 5 times.
So anyways, lost productivity and decline in workmanship because legally retarded niggers.
It was likely under .5% of ALL blacks occupied management roles in the 80s, but now...????
