Depends on the local. Lets say your local has 10 agents, and they match the UPS benny package. On August 1, your local needs to come up with an additional $40 per week per agent. That's $40 X 52 X 10 = $20,800. If they also match the raise of .70 @ 40 hrs we have .70 x 40 x 52 x 10= $14,560. That's $35,000 more than they spent last year. Along with those 10 agents they also have clerical staff, replicating these numbers. Plus utility bills, repairs, building maintenance, purchasing contracts, etc.
It adds up.
