Customarily and Regularly
•A frequency that must be greater than occasional but which, of course, may be less than constant •Includes work normally and recurrently performed every workweek
•Does not include isolated or one-time tasks
The phrase “customarily and regularly” means a frequency that must be greater than occasional but which may be less than constant.  Tasks or work performed “customarily and regularly” include work normally and recurrently performed every workweek; it does not include isolated or one-time tasks.
If a highly compensated “white collar” employee customarily and regularly performs one or more exempt duties, detailed analysis of all the job duties performed is not necessary.  For example, an employee may qualify as a highly compensated executive employee if the employee customarily and regularly directs the work of two or more other employees, even though the employee does not meet all of the other requirements in the standard test for exemption as an executive.
