At present, I have two jobs who are both competing on having me work which is only 4 days a month on weekends and I can barely pull off $100 a paycheck from either job. What I have goes to my car insurance, phone bill and gas just so I can make enough to get to work and back for two weeks if I'm lucky.
Yes, I am making that little right now. I have nothing, and I do mean nothing to spare. And yes I am actively looking for a better job and have been for the last month and a half. Only two prospects in that time which one is most likely not looking too good.
However since you mentioned that credit thing, it will be a good way to obtain something whenever I can find a means to have a little spare cash on hand but my work schedules are so unstable I never know what I am going to make month to month. It's not fun to be me right now.
