Help! day VS night shift, 8 hr VS 12 hr if want PRN later.

What is the shift I should choose for my full-time job.?

I just started my new grad internship in ICU. As you know, new grad starting salary is mimimum. Due to much higher income tax as a single person and lower payscale, I wouldn't earn much if I do only full time job. I have to do PRN or part-time some other place!!

After orientation is done or very soon, I will get to choose my permanant shift. I will never want to work weekends except for PRN. I want the shift that gives me chance to find another PRN job (I don't care whether PRN is M/S floor or ICU). I have energy to work. At first, I really want to work night shift for my full-time job due to $4 dollar shift differential but I think other hospitals won't need a lot of PRNs at night, right???

8hr shift may be a bad idea because I will have fewer days to work PRN somewhere else.

Just curious? In case I cannot find ICU PRN, I wonder if they will let me do the floor with if I have only ICU experience.

In fact, if I couldn't find anything PRN, I even consider go back to do my techs job PRN. At least, I can get $110/ day after tax..HA! HA!

PS. I am in Atlanta area.

Please help!
