United Auto Workers union is in its third day of striking against General Motors, demanding higher wages, better benefits, and a four-day work week.
The strike has affected more than 50,000 workers and 33 plants across the country.
UAW President Ray Curry said the union is ready to do “whatever we have to” to get a fair contract for its members.
He also thanked House Democratic Caucus Chairman Hakeem Jeffries, who visited the striking workers in Detroit on Friday.
The strike is seen as a test of the union’s strength and solidarity amid a federal corruption probe and declining membership.
