In California it is illegal to discriminate against an employee due to their real or perceived sexual orientation. Discrimination can take many forms. An employer cannot refuse to hire, fire, fail to promote, demote, discipline, or take any other “adverse employment action” against someone because of their sexual orientation or gender identity.
All young people, regardless of sexual orientation or identity, deserve a safe and supportive environment in which to achieve their full potential.

If a supervisor is committing the harassment, your employer is “strictly liable.” Under these circumstances while you do not technically have to report the harassment in order for your employer to be found liable, if you can do so safely, it is often wise to do so.
