People need to realize that the unions for white collar people like WGA or SIEU or NEA (public sector unions are why cops who kill the people they were supposed to serve & protect remain employed get pensions) is not the AFL-CIO or any other historical union fighting for the lives of the people who built the country's industry and made it run, any more than the NRA are the Minutemen of 1775 New England.
First, go fuck yourself, you fucking scab. No, seriously - you don't come to my blog and spout off about what workers deserve unions and decent pay and what ones don't, like it's your fucking decision. The intellectual labor that writers perform is just as real as any other work done on a film set - "all who labor by hand or brain" is the inherent logic of industrial unionism for a reason.
Second, writers aren't asking to get paid more than once: residuals are deferred pay, you absolute moron. In Hollywood, whether it's writers or actors or voice talent or whatever, you get a small fraction up front - it's usually an ok check, depending on the union's day rates and so forth, but you can't make a living off stitching these together - and then most of your pay comes from monthly royalty checks that provide you with the income you need to live off when you're between jobs.
The problem is that, historically in Hollywood, residuals have been structured with a very long "tail" - the payments start out relatively low and then get more generous over time as the show has more seasons and (presumably) goes into syndication. This doesn't work with streaming's new business model, where increasingly shows are getting 2-3 seasons max and streaming services have become increasingly quick to not just cancel shows but yank them off their servers in order to avoid paying residuals.
So what WGA writers are fighting for is a system that ensures writers (but also actors and other creative workers, because the unions pattern bargain) get a fair share of the show's revenue, even if the show is only given 2-3 seasons.
Third, the U.S labor movement would not exist today if it wasn't for white collar workers and public sector workers. About half of the U.S labor movement - 7 million workers - is public sector, and those workers are overwhelmingly women of color, mostly working as either teachers or postal workers. Likewise, about half the U.S labor movement is made up of white collar workers, and we're graduate students and adjuncts and lab researchers, teachers and social workers, administrators and IT departments.
I'm both public sector and white collar, and I'm a member of an NEA union. I'm an adjunct professor who earns $6,000 a course and it's my job to get working adults with jobs and families who've never gone to college or who've been out of higher ed for a decade to graduate with a bachelor's or a master's. If you don't think that's real work, you're free to research and write all the lectures and powerpoints, deliver those in an entertaining and educational fashion, answer a flood of questions from students who need help navigating academia, and then grade all the midterms and finals and research papers.
