In addition to farm labor, workers in the nation's food service industry garnered attention in 2012 and 2013 with a series of strikes against fast food outlets demanding higher wages, better working conditions, and the right to form unions. A study by the Labor Center at the University of California, Berkeley in October 2013 demonstrated that 52 percent of families of fast-food workers receive public assistance, in comparison to 25 percent of the workforce as a whole. According to the study, full-time hours were not sufficient to compensate for low wages.
