Mierle Laderman Ukeles has been working with the concept of maintenance art and maintenance work for decades, and wrote the Manifesto for Maintenance Art in 1969:
"After child-birth in 1968, Ukeles became a mother/maintenance worker and fell out of the picture of the avant-garde. In a rage, she wrote the Manifesto for Maintenance Art 1969, applied equally to the home, all kinds of service work, the urban environment, and the sustenance of the earth itself. She viewed the Manifesto as “a world vision and a call for revolution for the workers of survival who could, if organized, reshape the world.”"
