I see this where I work as well both with the nurses and the CNA's. It's so frustrating when people have such a crappy attitude, I don't understand why some people can't take pride in what they're doing. Nursing is so much more rewarding when you clock out knowing you did everything you could to take adequate care of your residents.
I have CNA's that will refuse to answer call lights, refuse to change people, and when you call them out on their bull **** they either say "I don't care." or report you for being "confrontational". Oh and of course there's the "I didn't have time." excuse even though they sat on their fat butts playing with their cell phone or went out to smoke 500 times.
I am fortunate that I do have shifts where the nurses and aides DO care and work together as a team to take excellent care of our residents. Man, I love those shifts. If only we could find a way to inspire some of the less motivated staff to look beyond themselves and take pride in what they do.
