The sources of current harassment regulations are reviewed, including the initial federal cases and the three key Supreme Court decisions. The Supreme Court decisions resulted in potential liability for employers who knew or should have known of harassment, though liability can be avoided if employer takes certain actions, including communicating a policy and training. Elements of an effective policy are reviewed and the distinction between training and communication is explained. California AB 1825 is reviewed, as well as laws in 14 other states related to training, and proposed legislation in other states. Employers must take certain factors into account in choosing between live training and Web-based training, including educational level of employees, cost factors, and degree of decentralization of the employee base. Pros and cons of both training styles are discussed, along with pros and cons of using attorneys as trainers, versus HR specialists and consultants.
