Exempt employees who are paid a salary are not always required to track their hours worked. However, you are not prohibited from asking them to track their hours. But keep in mind that salaried employees are paid a set amount for each pay period. You are not allowed to deduct pay from a salaried employer based on their actual hours worked. If you do this, they are not salaried, they are working on an hourly basis. The US Department of Labor goes into greater detail about this question in this article: Fact Sheet #17G: Salary Basis Requirements and the Part 541 Exemptions Under the Fair Labor Standards Act (FLSA)
