Dozens of protesters gathered this morning outside the North Side McDonald's demanding higher wages and joining similar demonstrations today in 150 U.S. cities.

Workers are calling for an hourly pay of $15 and the right to unionize, and organizers said some plan to walk off their jobs.

Workers in 80 cities in more than 30 countries -- including Argentina, Germany, India, Malawi, New Zealand and Panama -- are staging similar protests today, planners said.

In Pittsburgh, protests also are expected outside Wendy's, Subway and KFC restaurants.
