My in-laws turned on me for firing my sister from her job. She worked as a shop assistant in my shop.

They started cursing, like she's got a kid, raising her alone, how's she gonna live?! Is it all right that the bitch was selling the goods past the cash register and pocketing the money?

And all in all she took out more than 50,000 in two months?

Since she's got a kid, I should give her that money? I have nothing to pay the rent on and nothing to live on, as I only recently opened my own shop!

My parents are threatening to call the IRS on me if I don't get her back to work. This is fucked up! What do I do?
