I can't speak for ATI as a group,but I have been a freight dog for a lot of years and have seen a few things..I have never seen a subsidiary company,supposedly on the same rung in the company hierarchy, belonging to a different union, write a side letter to a contract dictating hiring practices,rates of pay and benefits and seniority and expect the other company to like it..The last guy recalled by ATI would have his seniority adjusted for the time he was furloughed,his vacation prorated and his pay adjusted accordingly. The first guy hired after him under this side letter from ABX would bring his current seniority for pay and vacations,etc,with him. How would that make our last guy called back feel to know the guy one number junior to him makes a lot more money and gets more vacation,sick days,etc..? I have never seen a guy quit one company and carry all this with him...Maybe I am missing something here, but the ability of a seperate airline,under a seperate union to write policy for another airline is something I just can't understand. Makes one wonder what else might be coming down the road if there is something else your "seperate company" decides to write a side letter about. Your contract is betweenyour pilot group and ABX, not the pilot group and ATSG.
