the workers here are not unionized. it therefore isn't a strike. we can safely assume that not all workers are participating in the walkout, and those that don't presumably still want work (orders) to come in.
i understand your pro-labor position (i am also pro-labor), but because this isn't a union effort, ie voted on and carried out by a singular work force, there aren't scabs. there are those who agree and those who don't. applying a disparaging label to those who chose not to participate is promotion of a one-sided message; a political bias.
also, wrt the amazon part of this news, it's a single warehouse in NY, and given that it's now 3PM there, and there is no news story of an actual walkout, it's safe to say that the effort fizzled.
