Squealing coming from brakes

Hello! I have a 2017 Hyundai Elantra that about a week and a half ago started having a squealing noise when i backed out and went driving down the road, braking, etc. It definitely isn’t to the grinding point yet.
My rotors themselves look like they’ve been damaged over the two years i’ve had the car, and are looking kind of crumbly and rusted.
I get paid on the 8th so that is when i’d be able to afford to fix them. I’m off work until the 6th, and the i have to make a half hour drive there and half hour drive home for work. I know it’s not recommended to drive on them but when i have to for those two days are there any good precautionary measures i can take??
I am absolutely freaked about it lol. Thanks!
