My brother-in-law works for me, but he refuses to work. What should I do?

This situation can only be that you can communicate well with your sister. Nothing is convenient for you to say. If your brother-in-law, maybe your brother-in-law has a problem with you, it will also affect your sister's family. If you don't talk about it, your brother-in-law's lack of ambition will also affect your family and you, so it is necessary for your sister to communicate. You still can't say anything.
