### Question
Please list the top three employees with the most unused sick leave along with their position titles.

### Hint
employees refers to BusinessEntityID; most unused sick leave refers to MAX(SickLeaveHours); position title refers to JobTitle

### SQL
SELECT JobTitle FROM Employee ORDER BY SickLeaveHours DESC LIMIT 3
