The biggest difference you will find is the number of residents that you are required to work with. Depending upon the shift, you can work with as few as six or as many as 30 residents at a time, either by yourself or teamed up with another CNA. Definitely you will not find the work atmosphere to be laid back and relaxed. Call lights are always going off. There is always something that should have been done half an hour ago. You will always feel like you are behind and unable to give the quality of care that you want to give. You may find yourself working with other CNAs who do not hold a very good work ethic. They may do things like hide in rooms when they are supposed to be making rounds. If you are a good worker, the charge nurses may grow to depend upon you to get a set of vital signs rather than hunt down the assigned CNA. Perhaps they do not even trust that particular CNA, so you may be caught picking up the slack.
Unfortunately, you will be doing this increased work load under less than perfect work conditions for about the same amount of money that you were earning working with one client as a HHA.
