Spreading Our Message At Remote Jobs

I'm sure this has been asked before, but how does one go about radicalizing and unionizing remote workers? I didn't join the union until I was remote all the time and I don't plan to go back to an office ever. Problem with that is there's no water cooler or smokers pit that employees can gather around and mingle. Sometimes co-workers might be across the country or globe. Does anyone have advice for someone wanting to radicalize/unionize people working remote?
