5 U.S.C. 5305 authorizes special pay rates for qualifying federal positions where recruitment or retention problems warrant them. It does not entitle every employee with a hard-to-fill occupation to an individually negotiated raise. Coverage depends on the approved rate table and position conditions. [1]
Rules that determine the answer
Special rates can vary by occupation, grade, location, agency, or other approved criteria. Locality pay and special rates generally are compared under the applicable pay-setting rules rather than simply added together. Statutory limits and special authorities can affect the ceiling; do not infer an uncapped payment from a listed percentage. [1] [2]
When changing jobs or duty stations, ask payroll to calculate the actual payable rate under the receiving position’s rules. A special-rate supplement may change even when the employee keeps the same grade.
What to check before taking the next step
- Find the current special-rate table and match the agency, occupation series, grade, geographic coverage, and effective date.
- Collect the SF-50, position description, duty station, pay table, and payroll calculation.
A distinction that changes the result
An approved special-rate table normally identifies the positions and locations it covers and its effective period. An employee should not apply a table merely because it has a higher number or a familiar occupational name. Pay-setting events such as promotion, reassignment, geographic move, and conversion can involve additional rules. Ask for a worksheet showing the selected table, step, applicable supplement, and payable limit. Comparing that calculation with the SF-50 is a more focused correction request than asserting that every similarly titled employee receives the same special rate. [1] [2]
Practical example
A special rate applies to a particular occupation in one duty station. A colleague with the same job title elsewhere may not be covered by that table.
