ernp, i have also worked mon-fri jobs in the past (as an rn not np). i agree that doing the 12s and having more time off is great and i don't feel completely tied down like i did with a mon-fri job. but my reasoning for thinking that i might like working mon-fri and getting home earlier is because when working the 12's, i miss my older son's school functions and sports. also, i have an hour drive and when i do 3 12's or even 2 12's in a row and don't get to see my 2-year-old twins but only in the morning briefly. that is my only reasoning. other than that, the 12's are definitely an advantage.
