Today I learned that programmers think that police and teachers unions are talent-based unions like the SAG.

That explains so much of the bizarre anti-union sentiment on HN.

Union rules part of some union collective bargaining agreements are that everyone who works there has to be part of the union. Many states that do have right to work laws still force companies to apply union agreements to even those who are not part of the union.

I would very much like to know which broadcast or cable shows you think use non-union labor, because that would be a violation of almost all studios agreements with the unions.

AFAIK, only Netflix uses non-union labor on shows...and even they have entered into negotiations with multiple unions.
