Because California recognizes gay marriage, the protections of the Family and Medical Leave Act apply to same sex partners. This is not currently the rule throughout the United States, but it may become official policy soon if a new proposed definition goes into effect.
The change to the FMLA policy would come after United States v. Windsor, in which the United States Supreme Court struck down the provisions of the Defense of Marriage Act, which denies federal benefits to same-sex couples who are legally married. It is part of a broader trend to ensure that gay and lesbian couples enjoy the same rights as straight couples when it comes to job benefits.
If you work in California, you need to be aware of the rights that the Family and Medical Leave Act provides to you. You should be eligible to take family leave if you have a qualifying covered event involving a same-sex spouse, a domestic partner, or a child of a domestic partner. If your employer fails to provide FMLA leave as required by law, you should contact an Orange County employment law attorney for help as soon as possible.
