Service Contract Labor Standards (SCLS)

Service Contract Labor Standards (SCLS), implemented under the McNamara-O'Hara Service Contract Act of 1965 (41 U.S.C. 6701-6707) and FAR Subpart 22.10, require contractors providing services to the federal government to pay covered service workers no less than the prevailing wages and fringe benefits established by Department of Labor wage determinations for the applicable service occupation and work location.

What are Service Contract Labor Standards?

The SCLS (commonly still called the Service Contract Act or SCA) applies to federal service contracts exceeding $2,500 where the principal purpose is to furnish services using service employees, janitors, security guards, food service workers, laundry workers, administrative assistants, mechanics, and other blue-collar and some white-collar service workers. SCLS does not apply to professional employees (engineers, accountants, scientists, managers) or construction workers (covered by Davis-Bacon).

DOL establishes wage determinations for each service occupation in each geographic area, specifying minimum wages and health and welfare benefit amounts. The applicable WD is incorporated into every covered service contract, and contractors and their subcontractors must pay covered workers no less than the WD rate for their occupation. If the contractor's established wage scale for a covered classification exceeds the WD rate, the WD does not reduce those wages, it sets a floor, not a ceiling.

A critical SCLS feature is successor contractor obligations. When a federal service contract is recompeted and a new contractor takes over, the new contractor is generally required to offer employment to the predecessor contractor's covered service employees (FAR 52.222-17, Nondisplacement of Qualified Workers). This right of first refusal prevents successor contractors from replacing the workforce with lower-cost employees as a mechanism to undercut the predecessor's cost structure. The new contractor must also pay at least the WD rates in effect at the time of the new contract, which may be higher than the rates in the predecessor's contract if wage determinations have been updated.

When a contract's wage determination is updated mid-performance (through an updated WD from DOL), the contractor is entitled to an upward equitable adjustment to the contract price under FAR 52.222-43 to cover the increased wage obligation, one of the few automatic price adjustment mechanisms available on FFP service contracts.

Why SCLS Matters for Government Contractors

SCLS compliance is one of the most complex administrative requirements in federal service contracting. Misclassifying covered employees as professionals (to avoid SCLS), paying below WD rates, or failing to provide required health and welfare benefits results in back-pay liability, civil money penalties, and debarment. Service contractors bidding on covered contracts must carefully identify which employees are SCLS-covered, verify that their proposed wage structures meet the applicable WD for the work location, and build WD-compliance costs into their cost proposals.

Example

A facilities management firm wins a $3.8M janitorial services contract for a federal office complex in Denver, CO. The applicable DOL wage determination lists janitors at $19.47/hr with a health and welfare contribution of $4.80/hr. The firm's Denver market rate for janitors is $17.50/hr base with $3.25/hr benefits, below the WD requirement. To comply with SCLS, the firm must pay all covered Denver janitors a minimum of $19.47/hr ($1.97/hr above its market rate) and contribute at least $4.80/hr in health and welfare ($1.55/hr above its current benefits). The differential for a 40-person janitorial crew working 1,900 hours/year is approximately $265,000 annually in additional labor costs, a material cost that must appear in the proposal price.

Frequently Asked Questions

How do I determine which of my employees are SCLS-covered?

SCLS covers "service employees" as defined at 29 CFR Part 4, workers who are not bona fide professional employees (exempt under the Fair Labor Standards Act), not executive or administrative employees, and who provide services (rather than supplies or construction). In practice, the line between covered service workers and exempt professional employees is drawn by job duties: a computer operator or help desk technician is typically covered; a software engineer or systems architect is typically exempt. Contractors should conduct a classification analysis for each labor category in a covered contract before the proposal is submitted.

What happens when the wage determination is revised after contract award?

Revised WDs may be issued during performance when DOL updates its prevailing wage survey data or when collective bargaining agreement rates change. Under FAR 52.222-43 (Fair Labor Standards Act and Service Contract Labor Standards), the government is required to adjust the contract price when a revised WD increases the contractor's wage obligation for covered employees. The adjustment is calculated based on the actual wage increase required by the revised WD multiplied by the estimated hours for covered employees in the affected classifications. The contractor must notify the contracting officer when a WD revision increases its costs.

Does SCLS apply to subcontractors?

Yes. Prime contractors are responsible for SCLS compliance by their subcontractors performing covered services. Primes must flow SCLS clauses down to all subcontracts for covered services and are liable for subcontractor SCLS violations. During proposal preparation, primes must obtain SCLS-compliant labor rates from subcontractors performing covered work and verify that the subcontractor's proposed rates meet the applicable WD for the work location.

What is the "bona fide fringe benefits" requirement?

SCLS requires that contractors provide a total compensation package (wages plus fringe benefits) meeting or exceeding the WD total. If the contractor's fringe benefit package (health insurance, retirement, vacation) provides benefits worth at least the WD fringe rate, it may pay the base wage rate without additional cash fringe payments. If the fringe benefits package is worth less than the WD fringe rate, the contractor must pay the difference in cash. Contractors must document the actuarial or cost value of their fringe benefit programs to verify compliance with the WD fringe benefit requirement.
