Events will also be held around the globe, with protests expected in 100 worldwide cities, 40 countries and on six continents.

Workers chose Tax Day, April 15, because many rely on public assistance to keep them above the poverty line.

“$15 an hour would help me greatly in school and especially in some of the things I also need like a car, clothes and especially paying for my rent,” McDonald’s employee Jose Paz said.

Students across the country will hold protests on campuses including both the University of California Los Angeles and Riverside, University of Southern California and LA Trade Tech Community College.
