100% it does. The stories my wife tells me about useless nurses and techs that do nothing and get paid top dollars is crazy. They are all protected. Every evening when she shows up for her graveyard, she always sees the same lazy nurses talking and playing facebook game on their department computers! (they send the new younger nurses to do the work). A few of the techs she works around basically refuse to go to ER to deal with patients and always send the younger ones. They take complete advantage of students who are doing their practicum.
Of course not ALL heath care workers are like this but quite a few are, mainly the "boomers". The department she works in has been building a case for over a year to have someone fired who consistently puts patents in danger. Some of the things this person has done over the last year would make your jaw drop. The fact it's taken this long is disgusting. That's Unions jobs for yah though I guess.
