Wanted to re-emphasize what the last poster said. You will want a degree if you're planning to go into HR. Any kind of administration work you'll want a degree. Instead of working two jobs, work 1 job and make school (degrees, trade certificate, whatever) your second job. It's a much better investment than earning an extra $100 bucks a week.

Take it from someone who got very lucky. I got passed up for multiple leadership positions purely because I hadn't finished an undergrad degree. If my manager hadn't gone out of her way to create a position that didn't require a degree in order to pay me more I'd still be stuck at my previous cap (in a job I loved, admittedly).
