The $800 million program — outlined in the "grand bargain" law that Gov. Charlie Baker signed last summer to avert several ballot questions — will allow employees to take up to 12 weeks of paid leave to care for a new child, tend to an ill family member, or cope with a loved one's active military deployment. Workers can also take up to 20 weeks to recover from a serious illness or injury or to care for a service member who is ill or injured. (See the types of leave that are eligible.)
