Nursing "branch" with the most flexibility.

Ever since I became a nurse I have had less and less time to help out with the family business which at times requires travel. I am still undecided which branch of nursing I want to settle in but flexibility is key. Right now my schedule if pretty rigid unless I go above and beyond to please my scheduler with extra shifts which makes me burn out quickly. Any ideas which branches of nursing are more flexible then others?
The most scheduling flexibility usually comes with working "per diem" as a staff nurse and/or in some sort of "float pool" or "agency" that allows you to sign up for as many (or as few) shifts as you want. You can make decent money that way and get the flexibility you seek ... but you will probably sacrifice your benefits (e.g. insurance, paid sick time, tuition reimbursement, retirement program, etc.). In those sorts of roles, you make a lesser committment to the employer, not promising to be there whenever they want you. In exchange for that lesser committment from you, they make less of a committment to you.
Yep, that's what I was going to say...per diem. I work per diem or contingent at all my jobs so that I can always match my husband's schedule. I'm lucky that I don't need health care benefits but I definitely miss the paid time off and I get called off a fair amount also, which is quite a hit to the paycheck.
Depends what kind of "time to travel" youre talking about and how frequentlyI think most nursing jobs are flexible enough, considering you can work 3 days a week to be full time. Hell you could work fri/sat/sun and still easily work 30-40 hours a week at a normal 9-5 job on top of that. But if youre talking about going away for 1-2 weeks on a whims notice , I dont think any fulltime job as a nurse will accommodate that. Especially since presumably youd be looking to start somewhere new with no seniorityIf you were on a unit for 20~ years and needed flexability im sure theyd work with you, but going somewhere new with that kind of baggage likely wont play wellPerdiem or some kind of part time might be your only realistic option
