I work 8 hours a week, 4 at starbucks and 4 at joanns. I’m looking for a new job because my paycheck for 2 weeks is 90$ from starbucks, and around 100$ from Joanns. How am I supposed to pay my bills like this?

(Edit) my hours are that low because of labor cuts, when I first started my second job I was at 21 hours a week, this is where I am now. I’ve asked for more hours they won’t give me any. My store manager doesn’t even work full time.
