Most live-in caregivers will need some time off each week/month for respite to reduce the chances of burnout. Their off time is their time to leave the house and have no duties or responsibilities, including, not being on-call. With that in mind, look over the below sample schedules and see which comes closest to your ideal schedule.
Lastly, don't pay too much attention to the sample start/end hours, as you can adjust these to suit your needs. For example, a shift can start at 6am instead of 7am, and end at 10pm, instead of 11pm.
Note: In almost all cases, CA residents are required to pay their live-in employee for their entire 8-hour sleep shift.
