Private Employers
The Office of Self-Insurance Plans (OSIP) authorizes qualified employers to provide their own coverage for workers' compensation liabilities. A private self-insurer is an individual private sector employer that has been issued and lawfully holds a valid Certificate to Self-Insure its workers’ compensation liabilities. California has one of the largest self-insurance programs in the nation and has some of the strongest regulations designed to ensure the system protects both employers and employees.
