We get this question all the time. Is a live in caregiver responsible to care for the senior during the night, or does another caregiver need to be hired to do the night shift?
A live in Caregiver can not be expected to work a 24 hour shift. If the senior requires care during the night, you do need to hire someone that can be responsible for the night shift.
If care at night is not required, and the caregiver is there only in case of emergency, most caregivers would be comfortable with that arrangement. You can possibly arrange with the caregiver that if an emergency ever comes up, you will pay her for her time.
Best of luck hiring!
