This report examines the decline in job-based health coverage in the United States and California, which is a crisis for working families. Working Partnerships USA (WPUSA), a nonprofit organization, was formed in 1995 to address the negative impacts of the Silicon Valley's economy on working families. The UC Berkeley Center for Labor Research and Education, a public service project of the UC Berkeley Institute of Industrial Relations, has produced research, trainings, and curricula to deepen understanding of employment conditions and develop diverse new generations of leaders. The authors of this policy brief acknowledge the support of the California Endowment and the Blue Shield Foundation of California in funding the research and development of this report.
