I am not sure about the colors, so I leave it up to the designers.
I have reference image with objects/layout idea. At the bottom of logo I imagine something a-bit-modern-technology-looking like. For example, a cog, as in Turkish Communist Party, which goes by the yellow color in my sketch and by number #1; Then, I image workers, teachers, medics merging into single fist, as per reference image, blue color, under number #2; It might be silhouettes of those people, depends on the overall logo aesthetic and colors you choice to make. But important to be able to differentiate between their professions, and to see them merging into one single fist. Then, this fist is holding capitalist cockroach, squishing it, similar to what we see under number #5, and banknotes are flying out from capitalist away. Under #3 in image we have logo name, which is actually going to be a website address, and #4 a slogan. The image might also contain some factories/industry thematic in the background or somewhere else integrated. Now, this reference has quite of elements already decided, so the main job here is to somehow put everything together aesthetically, with nice color play, to make overall sense of: "People, workers, unite squishing the capitalist in their fist". As for the rest of the package (headers, FB/twitter stuff, its all fully up to the designer, just make sure it matches the logo and is builded around it. Probably some factories/industry will work for the background theme just ine
