Fast-food workers in about 100 US cities will walk off the job this Thursday, organizers say, which would mark the largest effort yet in a push for higher pay.
The actions would build on a campaign that began about a year ago to call attention to the difficulties of living on the federal minimum wage of $7.25 an hour, or about $15,000 a year for a full-time employee.
The protests are part of a growing push by labor unions, Democrats and other worker advocacy groups to raise wages in low-wage sectors. Last month, President Barack Obama said he would back a Senate measure to raise the federal minimum wage to $10.10. That's more than a dollar higher than the $9 an hour rate he previously proposed.
Senate Majority Leader Harry Reid has promised a vote on the wage hike by the end of the year. But the measure is not expected to gain traction in the House, where Republican leaders oppose it.
Protesters are calling for pay of $15 an hour, although many see the figure as a rallying point rather than a near-term possibility.
It's not clear how large the turnout will be at any given location, or whether the walkouts will be enough to disrupt operations. Similar actions this summer had varying results, with some restaurants unable to serve customers and others seemingly unaffected.
The National Restaurant Association, an industry lobbying group, called the demonstrations a "campaign engineered by national labor groups," and said the vast majority of participants were union protesters rather than workers.
The group said that the demonstrations in the past "have fallen well short of their purported numbers."
Kendall Fells, a New York City-based organizer for Fast Food Forward, said demonstrations are also planned for 100 cities, in addition to the 100 cities where workers will strike. He said plans started coming together shortly after the one-day actions in about 60 cities this summer.
Organizers face an uphill battle in changing an industry that competes aggressively on low prices, a practice that has intensified as companies including McDonald's Corp., Burger King Worldwide Inc. and Yum Brands Inc. face growing competition and slow growth in the weak economy.
Fast-food workers have also been seen as difficult to organize, given the industry's high turnover rates. But the Service Employees International Union, which represents more than 2 million workers in health care, janitorial and other industries, has been providing organizational and financial support to the push for higher pay over the past year.
SEIU President Mary Kay Henry said she thinks the protests have helped encourage more states and localities to raise their minimum wage this year. She expects the number of cities and participants in the protests to grow next year as the union tries to keep pressure on fast food companies.
"I think we've totally changed the conversation about what these jobs are worth," Henry said. "These are no longer jobs being done by teenagers who need extra money. These are jobs being done by adults that can't find any other work."
