About ten years ago I worked at a warehouse doing pick and pack. They were and still are a hugely successful medical supplies company.
Pay was abysmal at less than $11 an hour so I took a mid shift that paid an extra .40 cents.
Those bastards in management adjusted the shift just early enough to avoid paying us that .40 cents shift differential. I had to go to third shift because I couldn't afford to lose that .40 cents.
The start time was set but we never knew when we would be released. From six hours to twelve depending on the workload assigned to us. How are we supposed to have a life outside of work if we never knew when we would get to leave?
We each had our own little packing station. No fan, no climate control, no seats. I tore a meniscus.
And raises? I learned how to operate a forklift and riding power jack. I learned how to inventory the deliveries input the outgoing orders into the computer. I was given a 2% raise when the annual reviews were given. Same as everyone else.
I was a robot with bills to pay.
