Elizabeth Warren unveiled a proposal Tuesday that would require companies to provide part-time workers with additional benefits and to adhere to “fair scheduling” laws.

The plan, Warren’s latest geared at working class Americans, would mandate employers offer 12 months of paid family leave for part-time workers and, for some, retirement plans after 500 work hours in two consecutive years.

The Massachusetts senator and 2020 Democratic contender also proposed barring companies with more than 500 workers from hiring new employees or contractors without first offering the additional work to existing part-time employees.

Warren said the plan “will help shift power back to part-time workers” and facilitate “the kind of big, structural change we need to create an economy that works for everyone.”
