They don't even need to strike. Just refuse to deliver anywhere BLM has rioted due to a legitimate fear for your physical safety. Then combine that with leftist cities setting a legal precedent for prosecuting people for self defense but not actually prosecuting violent rioters, and there's no reason for any truck drive to go near a blue urban area.

EDIT: Also, was at a flag waving rally for Trump on Saturday. 100% of big rig trucks giving the group a big thumbs up and blaring their horns. Not a lot of truckers riden' with Biden.
