Many of the unions in the entertainment industry are different from other unions in several ways. SAG and the SWG have nearly turned their entire industries into "closed shops", and a big part of their function is to be a barrier to entry for new talent (thus ensuring more work and higher pay for their membership) to the extent that working too much on non-union projects can lead to blacklisting.

To assume that members of these groups are necessarily supporters of "their" union or unions in general is flawed since members are required to join as a prerequisite to making a living in their chosen professions.

Also, to assume that anyone opposed to card-check is opposed to unions in general is flawed. If secret ballot elections are insufficient to the task of deciding labor organization, then why do we settle for such a poor way of selecting our government officials? Maybe all elections should be decided merely on the basis of voter registration rolls instead of wasting all that time and money campaigning, collecting and counting votes (after all, voters in elections are subject to coercion by campaigns and pundits for months leading up to the vote).

Further, the assumption that employers are the only ones with lawyers and political influence is flawed. AFL-CIO has as much money, as many lawyers, and more political influence than most of the employers their member unions go up against. In my own personal experience, getting rid of a bad union (I ended up working under their contract as a result of facilities consolidation by my employer following a merger, and had accepted the job under more favorable terms at a different site) took 3 weeks of grassroots employee-only activity to collect the requisite signatures to force an election, followed by an 18-month legal battle between the union/AFL-CIO and the employer/NRLB after which the election was finally held, followed by another 9+ months of legal fighting by the union to prevent certification of the election results (since they had lost by around a 2-1 margin even after a minor exodus of the most anti-union employees transferring to non-represented sites as a means of escape).

Perhaps the most flawed assumption is that unions, in their current form are actually concerned with looking out for the good of the workers (or even care about their much ballyhooed "solidarity"). A good number of guilds/unions have resorted to various tactics in order to bust the organizatrions representing their own office/clerical staff, not to mention scandals like Ullico (where the board made up of former AFL-CIO officials siphoned billions out of various pension funds and into their own pockets), and the AFL-CIO tampering with the Teamster's Union presidential elections trying to keep Jimmy Hoffa Jr. out of the office.
