I highly highly doubt that all 100,000 workers are striking. The article mentions that workers will strike and that it's being organized by Gig Workers Collective but I haven't ever found anyone indicating how many people actually participated in these strikes (Instacart workers recently did one)
It's says target gig workers will strike - no qualification or limitation whatsoever.
When fords union employees went on strike, they virtually all were on strike as well.
Is the headline really 99.5% of target gig workers do not go on strike? 0.5% go on strike? That's a BIG difference then everyone walking. They should at least do a follow-up with how many people quit or struck (50,000 or whatever).
