VFX people in Hollywoord are some of the most underpaid workers in the industry. Sure, it's cool that you can be a part of a team that helps make a movie. No doubt it must be pretty cool to see your work on the big screen, or even the small screen, and know that you played a part in bringing it there. But I think something the workers would also value is having some autonomy over their work, and being paid for it.
I'm not easily convinced by the argument of, "you get to work on cool stuff", working on cool stuff doesn't make up for risking povery, debt, or unemployment when you're underpaid. Furthermore, there's a difference between hard work, and exhausting working. And being put under crunch is exhausting work, not hard work.
