Most areas of nursing with low physical requirements have high experience requirements.
I work part time, 3p-11p shift in a SICU which at my hospital includes neuro. So critical trauma patients, stroke patients, surgical patients, occasional necrotizing wound patients who are septic and receiving hyperbaric O2 treatments.
I usually take a 30-minute break. I am on my feet a lot, but I do sit to chart or make phone calls. I started working in healthcare at age 18 as a CNA, and my feet were fine after the first few shifts. Actually I find walking on my feet MUCH easier than standing on my feet.
I really don't consider my working conditions to be poor though. Maybe because I like to read and I like history, and have learned about the working conditions in industrial revolution era factory work, in polar exploration, pioneer homesteading, maritime etc... nursing by comparison is cake!
I do protect my mealtime and water/bathroom breaks. Lots of nurses say they don't have time to pee -- and I have NO doubt that they are very busy -- I just have no trouble saying that pt requests, phone calls, M.D. requests etc can all wait 2 minutes. I usually don't take paid 15 minute breaks, but as long as I can eat and drink I'm okay with that.
I also don't work for facilities that mandate OT. One time in 20 years, I got stuck working 16 hours during a blizzard. That was reasonable -- it was a rare occurrence, and my colleagues who tried to come to work got stuck. Every single one. But I do NOT work anywhere where management fails to plan: "Hey, we got a sick call on nights, and it's your turn to stay." Um no. It's not my job to fill staffing holes -- only my job to work MY hours. Any additional hours are a favor to my colleagues, and always planned in advance.
Do I love working holidays? Of course not... and my kids hate it. But I think of it this way: retail workers, restaurant workers, convenience store workers also get stuck working holidays too. But they don't NEED TO, except that their employers have decided to be open. At least I know that my work is truly necessary.
Night shifts aren't unique to nursing either. I didn't like working overnight, but it wasn't horrible.
All that said, there are lots of options in healthcare if nursing is disagreeable, and all are important!
