I work on a med/surg floor. I often tell the aides that they get the least amount of money for the hardest work. CNA's make my job easier. If ordering out dinner I always pay for their food as a small gesture of appreciation for what they do. Often on our floor the RN will charge the patients on the floor and get our q4° vitals, if we are without an aide. The brief changing, repositioning, call bells, pitcher filling etc. falls on the primary nurse.
