I'm a student right now but I am a cca, I work full time nights. Nights are good as long as you're self-motivated. I am busy for my entire 12 hour shift starting with putting people to bed, getting laundry carts ready for the morning, cleaning up after the day staff. There are a lot of people, most are sleeping but I'm responsible to make sure everyone is dry in the morning, this means a lot of changes in the middle of the night. I want people to be looked after to my best ability, so I am on top of doing turns(q2h) and changes. Then to end our nights we have people who want to get up early and we get them up before we go.
It is easier on staff dynamics, not so many cooks in the kitchen.
