@quirk What exactly makes the Writers guilds around legitimate but doesn't apply to programmers?
Or are you going to argue that creative work isn't work?
Should they be abused just because they don't do as much manual labor? That'd be one hell of a weird take on worker rights.
As for a trade, I'd say any profession with a relatively narrow set of minimum skills which can be learned at a technikum would qualify.
@lispi314 the writer's Guild also is not a trade union, as writing is not considered a trade. There are also labour unions, but a labourer does not hold any specific trade designation, so a labour union isn't a trade union. People of every profession have the right to organize and form a union for their profession, but it's up to them to get the cards signed and get people out to vote. They can't do that working from their homes.
