Two tier is the start of the death of reg. full time drivers. If we allow UPSto have 25% t-sat drivers they wont have to hire any m-friend full time drivers until they meet the 25%. So...if thdy only utilize 15% and full fime drivers quit/retire they hire more t-s drivers until they hit the 25%. So by then this contract will be up and the nee three tier system will be introduced to faze out req drivers and have them replaced by t-s drivers at the lower wages. And the new w-sun drivers will earn even less. This means the fall of a full time driver being paid, compensated as we are now will cease to exist. Vote no.
