The McNamara-O'Hara Service Contract Act flowdown for federal service contracts over $2,500. Requires payment of locality-prevailing wages and fringe benefits to service employees, with DOL-issued wage determinations.
Citation: 48 C.F.R. § 52.222-41 · Live text on acquisition.gov · eCFR
FAR 52.222-41 implements the Service Contract Act of 1965 (SCA, codified at 41 U.S.C. chapter 67). It applies to most federal service contracts exceeding $2,500. The clause requires the contractor to pay each service employee performing on the contract not less than the wage and fringe benefit rates set in the Department of Labor wage determination incorporated into the solicitation. Service employees are defined broadly to include any employee performing services under the contract who is not exempt under the Fair Labor Standards Act (i.e., not a bona fide executive, administrative, or professional employee).
Wage determinations are issued by the DOL Wage and Hour Division based on locality-prevailing rates. They list specific labor classifications (e.g., Administrative Assistant I/II/III, Computer Operator, Janitor, Truck Driver) with corresponding minimum hourly wage and required fringe benefit rates. The fringe rate may be paid as cash or as the cost of bona fide benefits (health insurance, retirement, paid leave above SCA minimums). Holiday and vacation requirements are layered on top and have specific conformance rules.
SCA contract modifications and exercises of options can trigger wage determination updates. The contractor is obligated to apply the updated WD prospectively. Underpayment exposes the contractor to back-wage liability, debarment under 41 U.S.C. 6706, and potential False Claims Act risk if certified payrolls or invoices misstate compliance. The DOL Wage and Hour Division enforces, often through complaint-driven investigations and CO referrals.
Three tests resolve applicability. Read each in order; the first "no" usually means the clause does not flow.
1.Is the contract a federal service contract over $2,500?
If yes, the SCA generally applies and 52.222-41 flows. Some service categories (mail haulage, certain professional services, certain commercial services in specific contexts) carry exemptions; check FAR 22.10 for the specific category.
2.Is there a wage determination incorporated into the solicitation?
SCA coverage requires a WD for the relevant locality and labor classifications. Confirm the WD is current and watch for required updates at option exercise and substantive modifications.
3.Are the workers performing under the contract "service employees" under FLSA?
Bona fide executive, administrative, and professional employees (FLSA exempt) are not covered by SCA. Most blue-collar and clerical service workers are covered. The classification is fact-driven and not controlled by job title.
Patterns that produce questioned costs, back-wage liability, or False Claims Act exposure under this clause.
Job title does not determine SCA coverage. A worker called a "manager" who spends most of the day on covered service work is not exempt. DOL Wage and Hour investigations regularly reclassify workers and assess back wages plus interest.
Fringe can be paid as cash, but the cash-out approach must include all fringe-eligible employees consistently. Ad hoc cash-out for some employees and benefit provision for others, when not done under a documented policy, draws DOL findings.
Option exercises often require the contracting officer to update the WD. Continuing to pay the prior WD after the new one is incorporated produces back-wage exposure and FCA risk if billed against the option period.
When work classifications do not appear in the WD, the contractor must request a conformance from DOL. Self-classifying without conformance, then paying a guessed rate, is a recurring source of back-wage claims when DOL audits the contract.
SCA holiday and vacation entitlements have specific accrual and entitlement rules that often differ from contractor PTO policies. Substituting company PTO that nets out below SCA entitlement is non-compliant.
Specific signals that contracting officers, DCAA, and agency IGs use to surface noncompliance.
FieldLedger's signed timekeeping captures the SCA labor classification for each timecard, with the wage-determination rate locked in at award. The system flags option-exercise WD updates, surfaces fringe-cash-out vs. benefit-offset choices, and produces the payroll-vs-WD reconciliation that DOL Wage and Hour requests during investigations.
