Fast-food workers in Detroit walked off their jobs by the hundreds on Friday in protest of their current wages. Many of the restaurant chains had to temporarily shut down.

The employees of the Detroit fast-food restaurants, including Burger King, McDonald's, KFC, Taco Bell and Pizza Hut, followed fast-food workers in other cities—such as New York, Chicago and St. Louis—who have already taken action to increase wages. The Detroit workers hope to nearly double their pay—asking for $15 per hour, compared to their current wage of $7.40 per hour.

According to Thomson Reuters, more than 400 people showed up for the Detroit event, which organizers said caused several of the restaurants to temporarily shut their doors.
