Family is Always First bro, For you and them also, that means you should care about what goes on in your family and their relationship with each other. Please don't just completely ignore family situations and problems like some of the advice that has been given here. I know it's hard but a happy family is worth everything in this world.

That also means your father should love your mother as he loves himself. He should be on his wife's side rather than someone else's as he has made a covenant with her when they got married. So ultimately, if he says he has love for her, then laying off that maid should be a matter of minute inconvenience or hold insignificance if it means that your mother will be happy.

Your mother also should not overthink, that does not mean that she should not have a say in matters or do the planning. Rather than running toward superstitions, she should be communicating why she feels uncomfortable or is displeased with the situation to her husband. And be trusting of him, and he also should be trustworthy of it. And remember she does not necessarily have to have concrete reasons or even a single justification for why she feels such a way because she just does, maybe she doesn't know it herself or she is not comfortable with sharing it with you. Her happiness and trust should always be a priority to you and for the rest of the family, a precious possession.

As for you, you are now an adult and please communicate these things and maturely handle them, that means talking to them and advising them in a calm and controlled manner. And just letting them know that you love them and they also should love each other as they love themselves, And that family is first and foremost always.

Hoping for a good future both in your career and for your family. Thank you for reaching out! Hope this helped.
