McDonald’s employees and activists are rallying Thursday morning outside the landmark restaurant at Clark and Ontario in their fight for higher wages and the right to unionize.

Their so-called “Fight for 15” dollars an hour got a boost from a ruling by the National Labor Relations Board (NLRB).

The NLRB ruled that McDonald’s corporation acts as the co-employer of workers at its thousands of franchises.

As such, it can dictate wage levels paid by the franchisees.

McDonald’s argues that the ruling is wrong, violates the franchise laws in the U-S, and would change employment rules for all kinds of small businesses. The company’s statement says it only helps protect and promote the brand name and ensures food quality and availability for its restaurant owners.

The workers have support in city hall, where a move in on to raise Chicago’s minimum wage to at least 13 dollars an hour.

But the employees say that doesn’t represent a living wage in a city with a cost of living like Chicago.
