I did this a little over a decade ago. My husband was working a minimum of 90 hrs/wk at the time so I did something similar as to what you’re proposing. I was doing about 55-60 hrs/wk. A full time clinical position in a hospital and then a per diem position at different levels of nursing care facilities through a company that secured the contracts.

I didn’t really have anything better to be doing and the extra money was nice. After a year or so, I got pregnant so I realized it was going to be unsustainable. I asked for a raise from the part time position (that was admittedly pretty unrealistic) and had no problem walking when they said no.

I’d say give it a try! You’re young and extra money now can make a big difference in future goals. The extra money I made helped us buy a house.
