As a former UPS manager, I was directly involved in the exploitation of loopholes created in various Master Freight Agreements during the late 1980's and 1990's. In essence, this allowed UPS to divert massive volume on commercial accounts thru wholly-owned and partially owned non-union companies. This is the future of long-range UPS logisitical planning and that's why i began dumping my UPS stock long ago. The premium is still in expedited freight which has much better profit margins, but companies like Fed-Ex keep kicking UPS ass in that market. Nothing is permanent at UPS - including your job or your pensions.
