Understanding The Service Contract Act

The McNamara-O'Hara Service Contract Act (SCA) is a federal labor law that establishes wage, fringe benefit, and working condition requirements for contractors and subcontractors performing services under federal government contracts. The SCA was created to ensure that service workers employed on federal contracts are paid at least the locally prevailing wages and fringe benefits for the type of work they perform—preventing the federal government from inadvertently enabling wage depression by contracting with employers who pay below-market rates. The SCA applies to contracts and subcontracts with the federal government that exceed $2,500 and involve the use of service employees to furnish services within the United States. Service employees include workers in a broad range of occupations such as guards, janitors, food service workers, clerical staff, maintenance technicians, and other non-professional service roles. Certain categories of workers are excluded from SCA coverage, including FLSA-exempt professional, executive, and administrative employees, employees in positions with titles not subject to SCA wage determinations, and certain construction workers covered by the Davis-Bacon Act. For contractors in federally regulated service industries, understanding SCA applicability at the proposal stage is critical to accurate cost estimation and compliance planning. Aurora Training Advantage's Service Contract Act webinar with Wendy Sellers, SHRM-SCP, provides foundational guidance for federal contractors navigating SCA requirements.

The Service Contract Act's prevailing wage requirements are the core of the statute's worker protection mandate—they ensure that service employees working on federal contracts receive compensation reflecting the actual going rates for their occupation in the local area where the work is performed. Wage determinations under the SCA are issued by the Department of Labor's Wage and Hour Division and specify minimum hourly wage rates for each service occupation in each locality. These wage determinations are incorporated into federal contracts and must be paid to all covered service employees performing work under the contract. If a collective bargaining agreement (CBA) covers service employees performing contract work, the SCA requires that the contract successor pay the wages and fringe benefits established in the CBA for the duration of its term—a provision known as the CBA successor obligation. Contractors must pay at least the wage rates on the applicable wage determination even if the wage determination is higher than the CBA rates at the start of a new contract period after the CBA expires. Failure to pay prevailing wages can result in back wage liability, debarment from future federal contracting, and criminal penalties in cases of willful violation. Contractors should obtain and carefully review applicable wage determinations at the time of contract solicitation to ensure accurate cost proposals. Aurora Training Advantage's SCA webinar with Wendy Sellers provides practical guidance on reading and applying wage determinations.

In addition to prevailing hourly wage requirements, the Service Contract Act mandates that covered contractors provide health and welfare benefits and paid holidays and vacation leave to service employees at rates specified in applicable wage determinations. The health and welfare fringe benefit requirement is expressed as a minimum dollar amount per hour worked, and it can be satisfied through contributions to bona fide benefit plans such as health insurance, retirement plans, dental, or life insurance—or through a cash payment in lieu of benefits if no qualifying benefit plan is provided. The holiday requirement typically specifies a minimum number of paid federal holidays, with the SCA listing 11 federal holidays as the standard set. Vacation leave requirements increase with length of service with the contractor or any predecessor contractor: typically one week of paid vacation after one year of service and two weeks after five years. Importantly, under the SCA's successor contractor provisions, a new contractor taking over a federal service contract must recognize the length-of-service credit of employees carried over from the predecessor contractor for vacation accrual purposes. Contractors must verify that their benefit offerings satisfy SCA fringe benefit requirements as a condition of contract compliance. Fringe benefit shortfalls are a common source of back wage liability discovered during SCA audits. Aurora Training Advantage's Service Contract Act webinar with Wendy Sellers covers fringe benefit requirements in practical detail.

The Service Contract Act imposes specific recordkeeping requirements on covered contractors that are essential both for demonstrating compliance during audits and for defending against employee complaints or DOL investigations. Contractors must maintain records sufficient to establish that covered employees have been paid the required prevailing wages and fringe benefits for all hours worked on covered contracts. Required records typically include employee name, address, and occupation; the rate of pay and fringe benefits provided; the number of daily and weekly hours worked; and gross and net wages paid each pay period. Records must generally be maintained for at least three years from contract completion. The Department of Labor's Wage and Hour Division enforces the SCA and may investigate contractor compliance based on employee complaints or as part of audit programs targeting federal contracting agencies. Penalties for SCA violations can be severe: contractors found to have underpaid employees face back wage liability for the full amount owed to all affected employees, potentially covering multiple years and large groups of workers. Willful or repeat violations can result in debarment—a three-year prohibition from receiving federal contracts—which is a devastating sanction for businesses that rely substantially on government contract revenue. Cooperation with DOL investigations and voluntary compliance programs can mitigate penalties in appropriate cases. Aurora Training Advantage's Service Contract Act webinar with Wendy Sellers, SHRM-SCP, covers recordkeeping best practices and penalty avoidance strategies for federal contractors.

Achieving Service Contract Act compliance requires integration of SCA requirements into the business development, cost proposal, HR, and payroll functions from the earliest stages of the federal contracting process. At the bid stage, contractors must identify the applicable wage determination for the contract location and service occupations involved, and ensure that proposed labor costs fully account for required prevailing wages, fringe benefits, vacation, and holidays—since underbidding on labor costs creates compliance problems before work even begins. Contract award triggers the obligation to incorporate SCA requirements into employment terms, including written notice to covered service employees of applicable wage rates and fringe benefits. If the contractor is succeeding an incumbent on a federal contract, an analysis of CBA obligations and predecessor employee service credit for vacation purposes is required. HR and payroll systems must be configured to track SCA-covered hours separately if employees work on both SCA-covered and non-covered activities, and to apply the correct wage determination rates by location and occupation. Annual review of wage determinations is necessary when contracts are renewed, as rates are updated periodically. Designated compliance responsibility—typically in HR or contracts management—with clear procedures for monitoring, reporting, and correcting any deviations is best practice.
