How it works is UPS sends the list to the union with all of the employees and they are billed based off the list.
UPS doesn't just give anything to anyone, look at what they have done to their management team with the healthcare issue alone.
If it wasn't for the Union all of the hard working people at UPS would be making far less wages than what they are now with less vacation, no pension it would be a 401k instead that you would contribute not them, health care like what they did to their management team, etc.
Anyone who things they just give because they want to is dreaming. To get what we have has to be negotiated. Grievance forms, lights, going to negotiations/hearings and all the rest of it costs money.
In the Central helpers get $15 per hour it is far from minimum wage. They should have to pay just like the good union people working next to them.
