NEW YORK — Labor organizers say they’ve named McDonald’s and its franchisees in allegations of sexual harassment, marking their latest effort in a push to win higher pay and a union for fast-food workers.

The claims were filed with the U.S. Equal Employment Opportunities Commission on behalf of 15 workers who are part of the Fight for $15 campaign. The claims name McDonald’s Corp. as well its franchisees, reflecting a push to build a legal case that the company should be held responsible for conditions at franchised restaurants.

Fight for $15 is being backed by Service Employees International Union, and is seen as a way to open a path to unionization by identifying a single employer across the entire chain.
