The fast-food worker movement for higher pay is about to go global.

At a press conference outside a Midtown Manhattan McDonald’s on Wednesday, Fast Food Forward, a group representing U.S. fast-food workers, announced that workers from dozens of countries on six continents are joining the push for higher pay and workers’ rights.

The group announced nationwide strike plans for May 15 — a date which mirrors the $15 per hour pay they are demanding. On that same date, workers from dozens of countries on six continents will hold protests at McDonald’s, Burger King and KFC outlets. It is not known how many workers will strike, but thousands of the nation’s estimated 4 million fast-food workers are expected to take part in the one-day strike.
