IMHO. Unions are reactive to the movements of the company in nature. You cant tell them how to ruin their own business in most cases. Occasionally, something pops up like YRC freight where they are asking for concessions and the negotiation allows oversite in certain areas like mgmt. bonuses and stuff like that but those are rare. The system is what it is.
As ups has grown from a furniture delivery business, the union has had to make changes to meet their strategy. It will continue to keep updated but every once in a while it gets a curveball. It takes a moment to catch up to the curveball. There have been huge changes at ups in my career. Addition of air, 100 weight, 150 lb pkgs from 50 then 70 lb, , addition of freight and then freight sold, paper to DIAD and then now, GPS on boards when we had Book maps, pickup times, etc. Hell, when I started, we stayed out until you finished the truck and 9.5 was your best day ever. The union has always strived to stay up
