Workplace violence prevention training in California is required for nearly all employees of employers covered by SB 553. That spans retail, manufacturing, offices, warehouses, hospitality and other industries. Exceptions include employees teleworking from a location they choose. Certain small workplaces closed to the public with fewer than 10 employees are also excepted.

California Senate Bill 553, now Labor Code section 6401.9, requires covered employers to train employees on their Workplace Violence Prevention Plan. The training must include a chance for interactive questions with someone knowledgeable about the plan. It must be provided when the plan starts and at least annually after that.

Under California's SB 553, workplace violence is any act or threat of violence at a place of employment, including threats involving a dangerous weapon. SB 553 sorts workplace violence into four types by perpetrator. These are strangers with no business there, customers or clients, coworkers and former employees, and people with a personal relationship to an employee.

Warning signs of potential workplace violence include extreme mood swings, paranoia, increased alcohol or drug use, open threats, and threatening posts on social media. Sudden changes in a coworker's behavior should be reported promptly so management can offer support. The 15-minute California workplace violence video is available in English and Spanish.

No, California employers may not retaliate against employees who report workplace violence or seek help from law enforcement or emergency services. SB 553 requires the Workplace Violence Prevention Plan to include anti-retaliation protections and procedures for accepting and responding to reports. Employers should also keep reporters' identities confidential where possible.
