How do I talk to helper regarding her wake up late ? Everyday

Hi if you have spoken to her repeatedly and she doesn't listen I feel have to use threat . Tell her you will need to report her to the agency and send her back. Does she have alarm clock? Is she waking up late on purpose despite you already telling her not to? What time does she sleep by the way? Another method is to have someone physically wake her up everyday. Actually I feel don't have to think too much about how to tell her, just tell her you need her to wake up early at what time everyday and tell her to start doing the chores from that timing onwards .
