Back when I was working for United Parcel Service under the auspices of the Teamsters Union, where our hourly pay for unskilled labor was almost four times minimum wage (with full benefits), the non-Teamsters UPS foreman who were company men always said "please" and "thank you" when giving orders to us pack mules.
Strangely enough, as simple a curtesy as it was, it actually helped to sooth the usual labor/management friction. Although when real issues arose, the fallout could be downright dangerous.
So I can see both sides of this grievance: UMass police officers don't like being "inversed" to do work that is not spelled out in their contract, while their bosses want to ensure positive relations with the town of Amherst.
Meanwhile the hotspot areas saturated with students living off campus, don't get the full attention they deserve. And it's the neighborhoods that will suffer.
So can we "please" figure this out before UMass comes back in session?
