GREENVILLE, S.C. — As the Republican presidential hopefuls gather to debate in Greenville, low-wage workers again plan to march to the debate site as part of their campaign for higher pay.

Workers also plan to walk off the job at a local fast food restaurant prior to the debate on Saturday as part of their efforts seeking $15 an hour in pay and the right to organize.

Workers seeking higher wages have held demonstrations in various states in recent months when candidates appear or debate.

Demands for higher pay may be resonating with more Americans because typical household incomes have been stagnant since the mid-1990s.
