alt Hacker NewsOne of the major union leaders in the US—I forget exactly who; it might've been the head of the Teamsters, but this was a while back, so I don't have the details—has, in fact, called for a general strike, as soon as it can be effectively organized.
That's 2028.
General strikes are not something you can just Make Happen. They're certainly not something you can reasonably scoff at an individual (one who's not the head of a major union) for not having Made Happen. They require significant amounts of coordination between unions if you want them to have a prayer of success, and that takes a lot of time.
Don't denigrate protests of the sign-waving type. They are a very important rallying activity for the resistance. Among other things, they help ensure that people who want to fight back know they're not alone, and ensure people who want the fascists to win know their feelings are not universal.
General strikes are something you can make happen, as an individual, if you push others around you to follow you along. Sure, the US is lacking a lot in the department of having unions and a labor movement, but that doesn't mean it's somehow out of reach. The existing ones in other countries mostly started as grass-root movements, born out of a bunch of individuals going together and deciding they've had enough.
Relying on "union leaders" or political leaders of parties isn't gonna get you anywhere. What you need is active action, something that hurts the people who are trying to hurt you and non-violent protests every 6 months doesn't hurt them one bit.
I agree that protests are important, but they also have their time and place. When the government actively listens, then it's a great way to enact reform. Once the government stops listening though, you need to up your tactics, otherwise you're playing it straight into their pocket.
