Organizers of the fast-food protests for higher wages on Tuesday shifted their sights to another issue affecting workers: practices they say amount to "wage theft."

Protesters were set to rally outside McDonald's restaurants in cities including Boston, Chicago and Miami to call attention to the denial of breaks and other violations they say deprive workers of their pay.

In New York, roughly 50 protesters streamed into a McDonald's near the Empire State Building and chanted for a few minutes before being kicked out. It was a smaller showing than other protests over the past year.

The actions are part of an ongoing campaign by union organizers to build public support for a higher federal minimum wage.

McDonald's says in a statement its restaurants remain open "today — and every day."
