CAR days are for your own illness and can be accumulated up to 200 days. Members earn and can use 10 self-treated days per school year as long as they are on payroll. Self-treated days do not require a doctor's note. Three of the self-treated days can be used for personal business and/or to care for an ill family member (a total of 3; not 3 each).
Medically-certified days (and anything beyond 10 self-treated days) do require medical documentation.
Personal business is defined as something that can only be done during the school day, such as closing on a house. Personal business days should be requested in advance and the principal may ask the nature of the personal business before granting approval.
