A Yard & A Half Landscaping Cooperative was formed in 2013 to preserve and continue to develop a locally-owned, safe, just, and democratic workplace in an industry where workers often face exploitation, wage theft, and hazardous working conditions. Participation in the cooperative is a financial and career investment for members, not just a job. Worker-owners participate in professional development, learning transferable skills and creating economic growth and self-sufficiency. We also share in the profits of our labor, allowing us to reinvest in our own local economy, communities, and families.
