Managing cnas

It seems to me that you are getting pushback for holding people accountable for doing what they are being paid for. You don't say what type of facility that you are in, but I have seen many LTC facilities where the CNAs essentially run the place. They have been there longer than anyone else (because nurses don't stay), so they have cultivated relationships with management and/or ownership. If this is your situation, you probably aren't going to win. As soon as you ask an aide to do something that he/she doesn't want to do, they will just run to management. I know of one situation in which CNAs working at a LTC were directly observed taking supplies from the unit and loading them into their cars. When the RN reported it to management, she was basically told to mind her own business, that they would "never do that".

IMO you did not do yourself any favors by setting the precedent of being passive and doing the jobs of people who refused to work. That said, their lack of cooperation now is not necessarily a negative reflection on your managerial ability. Continue to hold them accountable, even proceeding with progressive discipline if the situation warrants it. Backing off will only ensure that you are working for them and not the other way around. If you are in a situation where management backs the CNAs, that is a battle that you will never win. Hopefully that isn't the case.
