Companies need to look at how much money they can save in salaries. When I worked there seemed to be one supervisor for every 10 workers, sometimes less. Then those supervisors had a supervisor, so now they can do away with most of the supervisor slots that did nothing other than tell employees no. So no first level supervisors anymore, with automation the secondary level supervisor should be able to track at least 30-40 people. After all school teachers kept track of that many.
