Overtime Pay Rules: Federal FLSA and State Requirements Guide

1. Federal FLSA Overtime Basics

The Fair Labor Standards Act (FLSA) is the federal law that establishes the baseline overtime rules for most workers in the United States. At its core, the FLSA requires covered employers to pay eligible employees 1.5× their regular rate of pay for every hour worked beyond 40 in a single workweek. This is the famous "time and a half" rule that has governed American labor since 1938.

Several foundational definitions determine how FLSA overtime is calculated:

• Workweek: A fixed, regularly recurring 7-day period (168 consecutive hours). The employer designates the workweek start day — it might begin Sunday at midnight, Monday at 8 AM, or any other fixed point. Once set, the workweek cannot be shifted week-to-week to avoid overtime liability. Trying to end the workweek early one week to cut off accumulating hours is an FLSA violation.
• Per-workweek calculation: Overtime is always calculated on a workweek basis. Hours cannot be averaged across two or more weeks. An employee who works 50 hours in week one and 30 hours in week two has 10 hours of overtime in week one and zero overtime in week two — not a 40-hour average with no overtime. This rule is frequently misunderstood by both employers and employees.
• Hours worked: All time an employee is required or permitted to work counts toward the 40-hour threshold. This includes pre-shift preparation time that is integral to the job, training that directly benefits the employer, and time spent on-call at the workplace (though on-call time at home generally does not count).

The FLSA applies to enterprises engaged in interstate commerce with at least $500,000 in annual business volume, as well as to hospitals, schools, government agencies, and domestic service workers. In practice, this covers the overwhelming majority of American workers — FLSA coverage is the rule, not the exception.

2. Who Is Non-Exempt and Eligible for Overtime

The default status under FLSA is non-exempt — meaning covered by overtime protections. Exemptions must be specifically established; they are not assumed. Understanding who qualifies as non-exempt removes confusion about who is entitled to overtime pay.

All hourly workers in covered enterprises are non-exempt from overtime. A warehouse worker, a retail associate, a restaurant cook, a hospital aide, a construction laborer — if they're paid hourly and work over 40 hours in a workweek, overtime is owed. Period. The rate of pay, the job title, and the employer's internal policies do not change this. An employer who posts a "company policy: no overtime without pre-approval" does not eliminate the legal obligation to pay overtime when it occurs — they still owe the 1.5× rate, even if they can discipline the employee for not seeking approval first.

Salaried workers earning below $684/week ($35,568/year as of 2024) are also non-exempt regardless of job duties or title. The FLSA salary threshold is a bright-line rule: if your weekly salary is below this number, you receive overtime protection automatically — no duties analysis required. This salary threshold is the most commonly misapplied rule in overtime law; many employers incorrectly assume that paying a salary automatically creates overtime exemption.

Part-time workers who exceed 40 hours in a single workweek are entitled to overtime. Being classified as "part-time" does not grant overtime exemption. If a part-time employee regularly scheduled for 25 hours per week works 48 hours one week due to a project crunch, those 8 hours beyond 40 must be paid at 1.5× rate.

Independent contractors are not covered by FLSA and therefore receive no overtime protections. However, worker misclassification — calling employees "independent contractors" to avoid labor law obligations — is aggressively pursued by the Department of Labor. The DOL uses an economic reality test examining multiple factors to determine true employment status. A worker who is economically dependent on one employer and operates under that employer's control is likely an employee regardless of what the contract says, and should receive overtime protection accordingly.

3. The Three White-Collar Exemptions: Executive, Administrative, Professional

FLSA's three primary overtime exemptions — commonly called the "white-collar" exemptions — cover executives, administrators, and professionals. All three share a critical structural requirement: they require both a salary test and a duties test. Meeting one but not the other does not create an exemption. Both must be satisfied simultaneously.

Salary basis test (all three exemptions): The employee must receive a predetermined salary of at least $684/week (as of 2024) that is not subject to reduction based on the quality or quantity of work performed. An employee who can have pay docked for poor performance, poor attendance, or slow weeks may not be on a true "salary basis" that qualifies for exemption.

Executive exemption duties test: The employee's primary duty must be managing an enterprise or a customarily recognized department or subdivision. They must regularly direct the work of at least two or more full-time employees (or equivalents). They must have the authority to hire, fire, or make recommendations that are given particular weight in hiring and firing decisions. Job titles like "manager" or "supervisor" do not automatically satisfy this test — the actual daily duties must reflect genuine management responsibilities.

Administrative exemption duties test: The employee's primary duty must be office or non-manual work directly related to the management or general business operations of the employer. The position must include the exercise of discretion and independent judgment with respect to matters of significance — not just routine clerical decisions or applying established procedures. An administrative assistant who processes paperwork according to fixed procedures is likely non-exempt. An HR generalist who independently makes compensation recommendations for new hires may qualify.

Professional exemption duties test: The employee's primary duty must require advanced knowledge in a field of science or learning, customarily acquired by a prolonged course of specialized intellectual instruction — typically meaning a four-year college degree or equivalent. Physicians, lawyers, engineers, architects, certified public accountants, and scientists generally qualify. Skilled tradespeople (electricians, plumbers) generally do not, because their knowledge is acquired through apprenticeship rather than intellectual instruction.

A separate Highly Compensated Employee (HCE) exemption applies to workers earning $107,432/year or more (as of 2024). HCEs are exempt from overtime if they customarily and regularly perform at least one exempt executive, administrative, or professional duty — a lower bar than the full three-part test for regular exemptions.

4. The Regular Rate of Pay: More Than Just Base Wage

The 1.5× overtime multiplier does not apply to just your base hourly wage — it applies to your regular rate of pay, which is a broader legal concept that encompasses all remuneration for employment except specifically excluded items. Misunderstanding the regular rate is one of the most common sources of overtime underpayment.

The regular rate must include: shift differentials (extra pay for night, weekend, or holiday shifts), non-discretionary bonuses (productivity bonuses, attendance bonuses, or any bonus that employees are promised or can expect as part of their compensation), and piece-rate earnings.

The regular rate may exclude: gifts (bonuses that are truly discretionary, where neither the fact of payment nor the amount was promised), vacation and holiday pay, overtime premium payments themselves, and certain expense reimbursements.

Failure to include non-discretionary bonuses in the regular rate calculation is a common FLSA violation, particularly in industries that rely heavily on productivity incentive pay. If your employer pays a weekly or monthly bonus tied to performance metrics and uses only your base hourly rate for overtime calculations, they may be underpaying your overtime.
