Defining a McJob: Fight for $15 protests planned for fast-food and other low-wage workers

The fight to redefine a McJob is heating up.

Labor organizers are planning their biggest day of protests yet for pay of $15 an hour and a union for fast-food and other low-wage workers.

The push on Wednesday comes just two weeks after McDonald's announced a pay bump for workers at its company-owned stores, suggesting the chain is also moving to take control of its image as an employer.

The Fight for $15 campaign is being spearheaded by the Service Employees International Union and began in late 2012 with fast-food workers. Since then, organizers have used the spotlight to rally a variety of low-wage workers, including airport workers, home care workers and adjunct professors. The say the demonstrations Wednesday will be in more than 230 U.S. cities and college campuses.
