ABF is the lead dog in this bargaining round, because YRC has a concession addendum until 2015. But YRC Teamsters will be affected by this contract, too.

YRC wages are pegged at 85 percent of the contract wage, and so will go up (or even down) with the contract. YRC health benefits, working conditions and job protections (or lack thereof) are on the line, too.
