My ex and I used to own a business. As I went about my daily business while running errands, I used to notice that there was a special place that postal trucks parked and the inhabitants took naps.
Why is this?
They have become efficient in delivering to their route. If they can do the route in 5 hrs. and the P.O. says it should take 8 hrs. then these union guys/gals don’t want to get back to early or their routes might get reevaluated. Meaning less hours less pay.
