No, you are not required to disclose your gender identity to your employer in California. Your gender identity is a personal matter, and you have the right to keep it private. California law, including the Fair Employment and Housing Act (FEHA), protects employees from discrimination based on gender identity and expression, regardless of whether you choose to disclose it.
If you do choose to share your gender identity with your employer, they are legally required to respect your identity, including using your preferred name and pronouns, and providing access to facilities that align with your gender identity. Discrimination or harassment based on your gender identity is illegal, and you have the right to report any violations.
In summary, you are not obligated to disclose your gender identity to your employer in California, and you are protected from discrimination whether you choose to share this information or not. If you face any issues related to your gender identity at work, consulting with an employment attorney can help you understand your rights and options.
