Response you can share with caregivers if they have questions about updating their schedule while on vacation.
If you go on vacation, you can update your general availability in your profile -- that way booking requests won't be sent to you. In the event that your agency wants to send a request to you specifically, they have that option. At that point you can just decline the booking.
Once you return from vacation, you'll want to make sure you update your availability so you start getting bookings again.
