Salaried employees may or may not be exempt from overtime, while all waged employees are nonexempt. Salaried employees are usually supervisory, managerial, or professionals who work on an annual basis and do not have an hourly pay rate. To be exempt from overtime an employee's main duties must be in managing the business or a recognized subdivision. Such an employee must be involved in the hiring and firing decision making. An administrative employee must have special expertise. Salaried employees are paid for the same amount of hours weekly regardless of how many actual hours they work-even if they work less than 40 hours. The employer may not reduce the salaried employee's weekly pay for business operations such as lack or work.
