Family medical leave act. It's a federal law that your employer has to give you up to 3 months off for your or a family member's medical issue. They have to hold your job or an equivalent position open for you during that time. It has to be supported by a doctor, but it's the law. It's unpaid time, but you can get vacation or sick pay if you have those. Also, the time doesn't have to be all taken at once, it can be spread out over time.
