1.4 Public Sector Payroll, Government Contract Acts & Youth Employment
Key Takeaways
- FLSA Section 7(k) lets public agencies use a 28-day work period of 171 hours for law enforcement and 212 hours for fire protection before overtime is owed.
- Public agencies may substitute compensatory time at 1.5 hours per overtime hour, capped at 480 hours for public safety, emergency response, and seasonal work and 240 hours for all other employees.
- State and local employees hired after March 31, 1986 pay mandatory Medicare-only tax even when a Section 218 agreement or a qualifying FICA replacement plan exempts them from Social Security.
- Davis-Bacon applies to federal construction contracts over $2,000 and requires a weekly certified payroll on Form WH-347; the Service Contract Act starts at $2,500 and Walsh-Healey at $15,000.
- Fourteen- and fifteen-year-olds may work no more than 3 hours on a school day, 18 hours in a school week, 8 hours on a non-school day, and 40 hours in a non-school week.
Public Sector Payroll, Government Contract Acts & Youth Employment
The Certified Payroll Professional (CPP) content outline treats the Fair Labor Standards Act and employment taxes as single domains, but three populations sit outside the ordinary private-sector rules and are tested heavily because practitioners rarely encounter all of them in one job: public agency employees, employees working on federal contracts, and minors. Each carries its own overtime formula, its own Social Security coverage analysis, and its own recordkeeping obligation.
1. The Section 7(k) Partial Overtime Exemption
Under FLSA Section 7(k) and 29 CFR Part 553, a public agency that employs people in fire protection or law enforcement activities may adopt a work period of between 7 and 28 consecutive days instead of the standard 7-day workweek. Overtime is owed only for hours worked in excess of a statutory ratio applied to that work period.
| Work Period Length | Fire Protection Threshold | Law Enforcement Threshold |
|---|---|---|
| 28 days | 212 hours | 171 hours |
| 21 days | 159 hours | 128 hours |
| 14 days | 106 hours | 86 hours |
| 7 days | 53 hours | 43 hours |
The ratios are simply the 28-day maximums prorated (212 ÷ 28 and 171 ÷ 28 hours per day). Two traps recur on the exam:
- The work period must be established and regularly recurring. An agency cannot retroactively pick a 28-day window after a heavy month to avoid overtime.
- Section 7(k) is a partial exemption, not a full one. Hours above the threshold are still paid at one and one-half the regular rate; the exemption only moves the trigger point.
Employees who spend more than 20% of their work time in a workweek on non-exempt activities unrelated to fire or police work lose 7(k) treatment for that period.
2. Compensatory Time in Lieu of Cash Overtime
Only public agencies may pay overtime with compensatory time off. Private employers cannot, and the practice of "banking" hours across workweeks in the private sector is one of the most common FLSA violations found on DOL investigation.
+-----------------------------------------------------------------------------+
| PUBLIC AGENCY COMPENSATORY TIME RULES |
| |
| ACCRUAL RATE: 1.5 hours of comp time per 1 hour of FLSA overtime |
| |
| MAXIMUM BANK: |
| - Public safety, emergency response, seasonal activity ....... 480 hours |
| (represents 320 actual overtime hours worked) |
| - All other public employees ................................. 240 hours |
| (represents 160 actual overtime hours worked) |
| |
| AGREEMENT REQUIRED BEFORE the overtime is performed: |
| - Union workforce -> collective bargaining agreement |
| - Non-union workforce -> individual agreement or understanding |
| |
| ONCE THE CAP IS REACHED: all further overtime must be paid in CASH |
| ON SEPARATION: unused comp time is cashed out at the HIGHER of the |
| employee's final regular rate or the average rate over the last 3 years |
+-----------------------------------------------------------------------------+
An employee who requests to use accrued compensatory time must be permitted to do so within a reasonable period unless it would unduly disrupt the agency's operations. Mere inconvenience or the cost of a replacement worker is not "undue disruption."
Volunteers present a related trap. Individuals who perform services for a public agency for civic or humanitarian reasons, without expectation of pay, are not employees. But an employee cannot volunteer to perform the same type of services they are already employed to perform for that same agency; those hours are compensable.
3. Social Security Coverage for State and Local Government Employees
Private-sector payroll professionals assume every employee pays both Social Security and Medicare. Public-sector coverage is layered:
| Coverage Situation | Social Security (OASDI) | Medicare (HI) |
|---|---|---|
| Covered by a Section 218 agreement | Yes | Yes |
| No Section 218 agreement, but participates in a qualifying FICA replacement retirement plan | No | Yes if hired after 3/31/1986 |
| No Section 218 agreement and no qualifying retirement plan | Yes (mandatory under IRC § 3121(b)(7)(F)) | Yes |
- A Section 218 agreement is a voluntary agreement between a state and the Social Security Administration, executed under Section 218 of the Social Security Act, extending Social Security coverage to designated groups of state and local employees. Coverage groups are defined by the agreement and its modifications, not by the payroll department.
- Mandatory Medicare applies to state and local employees hired after March 31, 1986, regardless of Section 218 status. Employees continuously employed since before April 1, 1986 may remain Medicare-exempt.
- The FICA replacement plan rules of Treas. Reg. § 31.3121(b)(7)-2 require a defined benefit plan providing a retirement benefit comparable to Social Security, or a defined contribution arrangement receiving at least 7.5% of compensation from employee and employer contributions combined.
The Student FICA Exemption
Under IRC § 3121(b)(10), services performed by a student who is enrolled and regularly attending classes at the school, college, or university employing them are exempt from FICA. Rev. Proc. 2005-11 provides a safe harbor: a student who is enrolled at least half-time and is not a full-time employee (generally, not normally scheduled 40 or more hours per week) qualifies. Career employees, postdoctoral fellows, and medical residents do not qualify; the Supreme Court settled the residents question in Mayo Foundation v. United States (2011).
4. The Four Government Contract Wage Statutes
Employers performing work for the federal government must layer prevailing wage obligations on top of the FLSA. Memorize the dollar trigger for each statute -- the exam tests them as a matched set.
| Statute | Covered Work | Contract Threshold | Core Obligation |
|---|---|---|---|
| Davis-Bacon Act (DBA) | Construction, alteration, or repair of public buildings/works | Over $2,000 | Pay locality prevailing wage plus fringe benefits, posted in the DOL wage determination; submit weekly certified payroll (Form WH-347) |
| Contract Work Hours and Safety Standards Act (CWHSSA) | Federal construction and service contracts | Over $100,000 | Overtime at 1.5x for hours over 40 in a workweek; liquidated damages per day per affected worker |
| McNamara-O'Hara Service Contract Act (SCA) | Contracts principally for services performed by service employees | Over $2,500 | Prevailing wage plus a separate health and welfare fringe rate; safety and health standards |
| Walsh-Healey Public Contracts Act (PCA) | Manufacturing or furnishing of materials, supplies, articles, and equipment | Over $15,000 | Federal minimum wage, overtime over 40 hours per week, child labor and safety standards |
[!IMPORTANT] Walsh-Healey no longer imposes daily overtime. The Act originally required overtime after 8 hours in a day. Congress repealed the daily overtime provision in 1986, leaving only the weekly 40-hour standard. "Overtime after 8 hours per day under Walsh-Healey" is a classic distractor.
The Copeland Anti-Kickback Act rides along with Davis-Bacon: it makes it a federal crime to induce a worker to give back any part of the compensation they are entitled to, and it is the statutory basis for the weekly Statement of Compliance that accompanies Form WH-347. Fringe benefits under DBA and SCA may be discharged either by making bona fide benefit contributions or by paying the cash equivalent, and the cash equivalent is included in the regular rate for FLSA overtime.
5. FLSA Child Labor Standards
The FLSA's youth employment provisions (29 CFR Part 570) are enforced independently of minimum wage and overtime, and civil money penalties are assessed per minor employed in violation and are indexed for inflation annually.
| Age | Permitted Work | Hour Restrictions |
|---|---|---|
| Under 14 | Only narrow exceptions: newspaper delivery, acting, working for a parent in a non-hazardous, non-manufacturing business, casual babysitting, wreath-making from evergreens | Not covered by the standard schedule |
| 14-15 | Non-manufacturing, non-mining, non-hazardous occupations listed in 29 CFR § 570.34 | 3 hours on a school day; 18 hours in a school week; 8 hours on a non-school day; 40 hours in a non-school week; between 7 a.m. and 7 p.m. (extended to 9 p.m. from June 1 through Labor Day) |
| 16-17 | Any occupation not declared hazardous | No federal hour restrictions |
| 18 and over | Any occupation, including the Hazardous Orders | None |
The Secretary of Labor has issued 17 Hazardous Occupation Orders covering, among others, power-driven meat processing and bakery machines, roofing, excavation, wrecking, and most driving. Payroll's practical role is to make sure the date of birth in the master file is captured and validated, to hold age certificates where the state issues them, and to route scheduling exceptions for 14- and 15-year-olds through a hard system edit rather than a supervisor's judgment. State child labor laws frequently impose tighter hour limits or require work permits; where the standards differ, the more protective rule governs.
