California law has changed once again, and now employers with five or more employees (including seasonal or temporary employees) must provide 2 hours of sexual harassment prevention training for supervisory employees and 1 hour of such training to non-supervisory employees.
The training must be completed by January 1, 2010, and then once every 2 years thereafter. This new law is from Senate Bill 1343, and is codified at Government Code sections 12950 and 12950.1.
