MIAMI -

Employees will walk off their jobs at a number of Miami's major fast-food restaurants for the first time ever Thursday.

Workers in Miami are joining strikes and protests in 150 cities across the U.S. They are calling for $15 an hour and for the right to form a union without interference from employers.

Clergy, local leaders and community activists will join and gather at the corner of Northwest 17th Street and Northwest Ninth Avenue near the McDonald's at Jackson Memorial Hospital at 11 a.m.

In the U.S, strikes are expected in cities from Los Angeles to Boston, including first-ever walkouts in Miami, Minneapolis, Orlando, Philadelphia and Sacramento. Around the world, employees are planning major protests in at least 33 countries spanning 80 cities.

The campaign started in New York City in November 2012, with 200 fast-food workers walking off their jobs demanding a pay increase.
