Ascribing a motive to the perceived negative side effect is a logical error. (By misrepresenting the union's position you've created a strawman, you've also appealed to motive rather than addressed the issue.) As is insulting the person rather than addressing the argument. (Appeal to ridicule, ad hominem, etc.)

And no, high school doesn't necessarily teach that. Nor does one have to agree that the checks and balances are unequal, or that power is imbalanced. Power is wielded by the different branches in different manners and in a way that's not easily measured if you look beyond the basics. Different founding fathers wanted different amounts of power in the hands of each branch.
