Supplemental RN or Float pool position? Please weigh in

I am currently a supplemental RN on a surgical floor and would like advice regarding a possible change of position based on a few reasons.

I enjoy the floor I work on, and up until January I have worked 4-5 days per week, one weekend per month. I do not have any benefits, although working as a supplemental, I get about $4 more per hour. I do not have health insurance.

My schedule now is 1-3 days per week.

I have applied and interviewed for a float pool position. This would consist of five 12 hour shifts per pay period. I would receive health insurance, gain PTO, learn new things like cardiac, and cross-train in the ER, etc...but I would have to work every other weekend, and work 12 hour shifts (but more days off during the week).

I definitely need health insurance. If I bought it through the exchange, it would cost me $300/month. Some months I make $300-600 in supplemental pay. Insurance through work would be around $100-or less- and I could add my son too, dental included.

Which option would you go for? Flexibility in hours, but no guarantee of hours, higher pay, and one weekend a month?

Or guaranteed hours (but longer), work in new fields, have insurance, and work 2 weekends per month instead of one?

This decision is killing me! Who knows, anyway--maybe I will not even be offered the position! (She makes the decision Monday or Tuesday next week).
