The strike called for immigrants not to go to work, to avoid spending money, and keep children home from school.  People took part to show the importance of immigrants to the economy and also to protest possible racial profiling of U.S. citizens by immigration enforcement.  The strike was planned on social media.  People first started talking about the strike after the Women's March, and as the idea gained momentum, important people in the restaurant industry helped boost exposure.
