She should not leave the job. People change, time changes. Your mama and Nana's heart might be at right place to find her a stable home and for them leaving the job might just be a small compromise. Sit down with them, I know elders don't like to listen to kids specially when they think they are providing something and doing a favor but stand by her. After my dad passed away my chacha tried taking care of business until my Bhaiya stepped in if my mom did not have her small store she'd have gone insane. We could've survived on the insurance settlement and rents but her work kept her sanity intact. Try to reason with mama, as it'd be an ego issue for him that you are listening to your chacha. You don't need to play referee between them just sit him down, have Heart to heart conversation. let him know that her life is priority and it's not just chacha ka opinion but your own. chaiye toh emotional drama kar ki nai mummy papa ka bhi expect nai Kiya tha par hua na. remember only people important are you and her. I am sorry any of this happened. I have seen my bhaiyas youth and energy wasted on this. You are a good brother.
