After you adopt, what about job security while staying home with your new child? The Family Medical Leave Act may provide the benefits you need. The Family Medical Leave Act (FMLA) of 1993 is a federal law that requires employers of more than 50 workers to give full-time employees up to 12 weeks of unpaid leave for the birth or adoption of a child. One must have been employed for at least 12 months and worked at least 1250 hours during the previous 12 months. Your employer may have more generous benefits, but this offers minimum protection.
