I'll tell you like I was told in LPN school . Don't go into nursing for the money. Yes you probably can make $60-70K But you'll work for it. You won't come out of school making that kind of money and when you get to that level you will be maxed out.
Go into nursing if you want to help people, if you care about others, and if you don't mind working weekends, nights, and holidays. If you don't mind being treated as inferior by many docs. That is improving though I will say.
As for unions. Unions are only as strong as their members. Nurses are not notorious for "getting along". Remember it's mainly a woman's field. And you know what's it's like having two women in the kitchen.
Go into nursing for the art of nursing. Not for money you won't be happy if you do and all that money won't be worth it.
