A lot of the current strikes are over the two-tiered systems and companies are using the two tiered systems to slowly push out the unions. Two-tiered systems allow some workers to be full union members, but new hires not with the promise that one day they may become union members. Non-union members are mostly making way below those of union counter parts doing the same job. Then what happens, someone from the union retires, so a lot comes open for a non-union member, but the company never fills it. They can meet their promise with the union of "we have 5,000 union jobs on paper," but they don't actually have 5,000 union workers because they are not filling them.
