I think some ppl view it as a starting point, bc it's so physical it would hard to be a retiring time job when one is older. The social aspect can be hard for some, some of these people are here so often they work the system, while management is pushing for hotel customer service. Add that to an increased acuity level, and it can be tough.
It's that toughness that will make you stronger. I've been working med-surg for about 5 years, i'm gearing up for a switch, but it def took me some time to feel comfortable managing it all. I work on a 36 bed unit, and often charge.
