Striking generally only works for skilled workers. Unskilled workers going on strike in the middle of some of the highest unemployment figures recently seen is not going to end well for those people. They'll simply be replaced by those who are more hungry.
This is not a problem with the workers, or with the employers, or with the current situation: it is a problem inherent to unskilled, undifferentiated labor.
