Sick Leave for Exposure to Communicable Disease. An employee is entitled to use sick leave if health authorities or a health care provider determine that the employee's presence on the job would jeopardize the health of others because of exposure to a communicable disease.

Usually, these programs allow the employee to take three to four personal holidays per year to conduct personal business or just to get away from the hustle and bustle of the office for a day or two.
