Fast food workers are striking. That’s not a sentence I thought I’d ever write. While the strike “movement” dates back to November, a wave of walkouts this week has upped the ante considerably. In November it was New York City. Recent actions have taken place in Chicago, Washington, D.C., St. Louis, Kansas City, and Detroit at chains including McDonald’s, Taco Bell, Popeyes, and Long John Silver’s.

The main demand: higher wages of up to $15 per hour.
