Considering my fiancé is on his way to making double the minimum wage and I've already done the 12+ shifts in the past, it would be a pretty healthy addition to our combined income, plus that would mean overtime, even double time if it's seven days a week.
I actually enjoy working, anyway. As long as the shifts don't conflict and there is always one of us home at any given time, I'd do it without hesitation.
Edit: Also, it was never specified which people I would be living with, so I can easily say it's just me, my daughter, and my fiancé in an apartment together. If it has to be outside of that, then my best friend, her kid, and her husband. There are 4 bedroom apartments here and they are actually quite nice and pretty affordable.
