DFEH Releases Workplace Harassment Guide For California Employers

Today the Department of Fair Employment and Housing (DFEH) released a Workplace Harassment Guide. The new guide, available here, provides recommended practices for preventing and addressing workplace harassment. The guide was developed by DFEH’s California Sexual Harassment Task Force, of which Amy Oppenheimer is a member. It provides insight into employer responsibilities addressed in the new Fair Employment and Housing Council (FEHC) regulations enacted in 2016.

The guide will be instrumental in providing employers with practical advice as to how to prevent and investigate workplace harassment and is one of the few such guides available to employers that has the imprimatur of a government agency. It will help employers comply with their obligation to take reasonable steps to prevent and correct workplace harassment.

As workplace investigators, our office is pleased to have such an important resource and proud that Amy contributed to this groundbreaking guide. Check out our blog for more on this.
