As an artist I'd love to see suggestions in this thread. The specific recommendations might be different country to country or smaller districts. Something thats difficult for the US is that a lotta people are doing jobs related to tech and there's not really a single unifying symbol for this. Hammer and sickle to represent farming and manufacturing is possible, and I believe adding a brush branches out to a wider movement.

But finding symbols to speak to the workers as a whole can be difficult with how diverse it all is. Theres so many hyper specialized machines and tools.

When making Icons before I've used my states iconography and Black panthers, and queer symbols like the pink triangle. This is extremely important and a good symbol will speak to the audiences you want and pull dedicated people into the movement.

It might be necessary to focus on smaller regions within the US and Unite those before creating broader movements. (OFC whichever is in the best interests of the end goal of revolution at that time.) I can only speak to the US however
