I've worked day and evening shifts in my current position. I've done a night shift as a home care assistant.
Honestly, the day shift is fast paced and the shift goes quickly if you are the bath aide or doing other tasks. Evenings are not as fast paced but still busy. And yes, it depends on if tasks were done on the previous shift. I was the bath aide on one evening shift because an aide didn't come in on day shift. This happens unfortunately.
It depends on the needs of the SNF and definitely talk to your coworkers and the nurses on duty about your situation.
