Trickle down economics not easily explained

Let me explain.
Dedicated cooler packers, bread bagels produce, complaining about 14 years service and $18 an hour.
All told, same shortages daily.
Huge margins of error, because windows of opportunity too small.
Or, small windows filled with ancillary work. Busy work.
Two and half hours shaved from following day's production; translation, more relaxed production environment..and less mistakes.
Reduced production day; labor cost saved.
Pissed off ESL, and no changes in management turnover.
Welcome to manufacturing.
