Last April, forty-eight members of the Harvard Living Wage Campaign installed themselves in the university’s main administration building to protest the university’s labor policies and demand wage increases and benefits for the school’s lowest paid workers. After twenty-one days of rallies, civil disobedience, and community organizing by workers, unions, students, and faculty, the university agreed to substantive improvements in working conditions. Making use of student footage shot before and during the sit-in as well as news coverage, archival footage, and worker portraits, Occupation follows the story of the longest sit-in in Harvard history, giving special attention to the effects of low wages on workers and their families.
