Important Workshop: Harassment Prevention Training For Supervisors. Don't miss this important information that is required by state law. Governor Newsom recently signed legislation that would extend the deadline for employees—supervisory and nonsupervisory—to be trained by January 1, 2021. The deadline was not extended for employers of seasonal and temporary employees who are hired to work less than six months. They must be trained within 30 calendar days after their hire date or within 100 hours worked (whichever occurs first).
