US has an organization planning a national strike on October 15th. Their site is down. The tone is less of specific demands and more of general ire.

As pointed out in [1] a wild fire [2] ended public support of a boycott. I personally lived in the area affected by the strike, but with the hours I worked I could not be choosy enough about where I bought food to add "support strikers" to my calculations, and then the fire [2] made any extra driving related to labor organizations' wishes borderline illegal and definitely antisocial.
You will also read in [1] that the supermarkets that were struck might not as easily be affected by a strike if it happened today.
