Claim for Retroactive Compensation while Performing Higher Level Duties

A federal employee requested reconsideration of a settlement denying his claim for retroactive compensation for performing higher level duties over a 7 month period. The employee should have appealed the alleged improper classification to the Civil Service Commission. The denial of the claim was sustained since the employee was not officially detailed, did not possess the qualifications for the higher level position, and did not meet the time-in-grade requirement of the Whitten Amendment.
