I'm not trying to beat up on you, personally, but see, that's the thing; members of strong unions don't fret about the individuals hired by management to negotiate against their union because it simply doesn't matter.
Members of impotent, useless unions, on the other hand, complain about management hiring the likes of Jerry Glass/Weel/Brundage, etc. Why? Because the impotent, useless leaders of their impotent, useless unions offer it up as yet another excuse. And members buy into their endless excuses. "We'd do better for you if management wasn't so unfair in hiring such effective negotiators." See how ludicrous that sounds? Your union is admitting that its success hinges on management hiring weak, impotent, ineffective negotiators to represent the company.
Because I know that my union negotiates effectively on my behalf, I couldn't care less which union-busting big-shot is hired by management. And my union has never tried to make excuses by claiming "management is unfair because there's no way we can counter their big-name hired guns." My union leadership would be back on the floor in a minute if they said anything that stupid.
