A $25-an-hour wage for healthcare workers in California would be an average 31% increase, according to the UC Berkeley Labor Center.

Enrique Lopezlira, a labor economist and director of the low-wage work program at UC Berkeley’s Labor Center, said housing prices will likely become more central to unions’ concerns as service workers are forced to live farther away from their place of employment.

Jane McAlevey, a senior policy fellow with the University of California, Berkeley Labor Center, said something as seemingly small as a snack-price increase could be meaningful to a low-wage worker who might interpret it as “someone sending us a message, we’ll make your life harder as you’re making demands for fairness.”
