I'm an RN/RM and I've always said that hospitals need to start pulling their fingers out and offering family friendly hours, it's no wonder people are leaving the profession
If they offered shifts say from9-2 or 3-11pm they would have so many more options. And people would be happier
My workplace do a floater shift frim8pm-2am which is very popular with mums.
But it is hard with family and shifts, especially if you're a single mum.
A lot of the mums I know do nights and weekends. I guess it depends how old your children are etc.
Good luck in whatever you decide
