i called my local nicu just to see the requirements for hiring in the nicu (caromont healthcare in gastonia nc) if they use any cnas or if they only use rns. she told me you have to be a sec/tech and that they only use cnas in in the birthplace (healthy born babies). i have been a cna since 2002...and i have applied for positions in the past for unit secretary and got it. but she was acting like a sec/tech is something specialized. can someone tell me what is the difference if any.
