Can’t interview because I always work.

I sometimes see where people write, “why don't you just get a different job?” As if it's a galaxy brain idea. My problem recently is, it's generally difficult to find available times for interviews. I work 7am – 7pm 5-7 times a week. I can't just quit because I need money. I also find it hard to take PTO, because I have so little I need it for emergencies that may arise. I'm sure there are plenty of people in this same boat. So, when you ask, “why don't you spend 20-30 hours a week applying, getting dresses up, and interviewing?” this is my answer.
