The Fair Labor Standards Act (FLSA) is the primary federal law that governs how most employees in the United States must be paid for the time they work. It defines what counts as hours worked, when overtime is owed, the minimum wage that must be paid, and the records employers must keep to document compliance. It applies broadly to employees in the private sector and in federal, state, and local governments.

Core Purpose and Scope of the FLSA

The FLSA was enacted to set nationwide standards for basic wage and hour protections, including:

  • Minimum wage requirements for covered, nonexempt workers
  • Overtime pay when employees work more than 40 hours in a workweek
  • Recordkeeping obligations for employers regarding hours and wages
  • Youth employment restrictions intended to prevent oppressive child labor

These rules are enforced by the Wage and Hour Division (WHD) of the U.S. Department of Labor, which investigates complaints, issues guidance, and may pursue back wages and penalties in cases of noncompliance.

Employee Coverage: Exempt vs. Nonexempt

Before determining how an employee must be paid, employers must understand whether the employee is covered by the FLSA and whether they are classified as exempt or nonexempt.

Coverage Under the FLSA

The FLSA applies to most employees engaged in interstate commerce or who work for businesses that meet certain enterprise coverage thresholds. In practice, this includes the vast majority of U.S. employers in retail, service, manufacturing, health care, education, and government.

However, there are categories of workers not covered by the FLSA or treated differently, such as certain independent contractors and specific occupations defined by statute.

Nonexempt Employees

Nonexempt employees are covered workers entitled to the FLSA’s wage and hour protections. They must receive at least the federal minimum wage for all hours worked and overtime pay for hours over 40 in a workweek.

  • Generally includes hourly workers and many salaried employees who do not meet exemption criteria
  • Must be paid for all hours worked, including certain preparatory or follow-up activities and some off-site work
  • Eligible for overtime at not less than 1.5 times their regular pay rate when they exceed 40 hours in a workweek

Exempt Employees

Exempt employees are not entitled to overtime pay under the FLSA. Common exempt categories include executive, administrative, professional, certain computer employees, and outside sales roles, provided they meet specific duties and salary tests.

  • Usually paid on a salary basis above a specified salary threshold
  • Perform primarily executive, administrative, or professional duties as defined by regulation
  • Not required to receive additional pay for working more than 40 hours in a workweek

Misclassifying nonexempt employees as exempt can lead to substantial liability for unpaid overtime and penalties. Employers should periodically review job duties and pay practices to ensure proper classification.

Minimum Wage Requirements

The FLSA establishes a federal minimum wage that sets the floor for hourly pay. Covered nonexempt workers must receive at least this amount for every hour worked.

As of July 24, 2009, the federal minimum wage is $7.25 per hour and has not been increased since that date. Many states and some local jurisdictions have adopted higher minimum wages. When both state and federal minimum wage laws apply, employees are entitled to the higher applicable rate.

Interaction with State and Local Laws

Employers must:

  • Determine whether their employees are covered by state or local minimum wage laws
  • Compare federal, state, and local minimum wage rates
  • Pay the highest applicable rate to each employee

For example, if a state’s minimum wage exceeds $7.25 per hour, that higher state rate must be paid to covered employees, even though the FLSA sets the federal minimum at $7.25.

Defining the Workweek

The FLSA applies its wage and overtime standards on a workweek basis. A workweek is defined as a fixed and regularly recurring period of 168 hours, or seven consecutive 24-hour periods.

  • The workweek can begin on any day and at any hour, but once established it should remain consistent
  • Overtime eligibility is measured separately for each workweek
  • There is no averaging of hours across multiple workweeks

This definition is critical for determining when overtime is owed and for maintaining accurate time records.

What Counts as Hours Worked?

The FLSA requires employers to pay covered, nonexempt workers for all hours worked in a workweek. While the statute does not list every possible scenario, case law and Department of Labor guidance clarify that hours worked generally include:

  • Time during which an employee is required to be on duty
  • Time the employee is permitted to work for the employer, even if not requested
  • Certain preparatory and concluding activities integral to the job
  • Some work performed off-site, such as job-related tasks from home

The key question is whether the time benefits the employer and is controlled or allowed by the employer. If so, it is typically hours worked and must be compensated.

On-Duty and Assigned Work Time

All time during which employees are required to perform their assigned duties is clearly hours worked, including:

  • Regular scheduled shifts
  • Mandatory meetings and training sessions related to the job
  • Required travel between job sites during the workday

Unauthorized or Unrequested Work

Employers must pay for work they allow employees to perform, even if the work was not specifically authorized. The FLSA focuses on whether the employer knows or has reason to know the work is being done and benefits from it. In those situations, the time is generally compensable, although employers may discipline employees for violating policies about unauthorized work.

Waiting Time, On-Call Time, and Breaks

Although the source article focuses broadly on hours worked, a few general principles help determine whether waiting or on-call time is compensable:

  • Waiting time where employees are not free to use the time effectively for their own purposes is often treated as hours worked
  • On-call periods may be compensable if the employee’s freedom is significantly restricted
  • Short rest breaks of around 20 minutes are usually considered hours worked and must be paid, while bona fide meal periods are typically unpaid if the employee is completely relieved from duty

Employers should consult official Department of Labor guidance for specific scenarios and industry practices.

Overtime: Time-and-a-Half After 40 Hours

One of the most important FLSA requirements is overtime pay. Covered nonexempt employees must receive overtime for hours worked over 40 in a workweek.

Aspect FLSA Overtime Rule
Trigger point More than 40 hours worked in a single workweek
Rate of pay Not less than 1.5 times the employee’s regular rate of pay
Workweek definition Fixed period of 168 hours (seven consecutive 24-hour periods)
Hourly limit No limit on hours for employees aged 16 and older
Weekend / holiday work Extra pay is not required solely for weekend or holiday work, unless total hours exceed 40

Calculating the Regular Rate of Pay

The regular rate is more than just an employee’s base hourly wage. It typically includes all compensation for employment, such as non-discretionary bonuses or incentive pay, divided by the total number of hours worked in the workweek. Employers must calculate overtime using the correct regular rate to avoid underpayments.

State Overtime Laws

Some states impose more protective overtime rules, such as daily overtime after a certain number of hours in a day. When state and federal rules differ, employers must follow whichever rule provides greater overtime benefits to the employee.

Recordkeeping Obligations

Accurate and complete records are essential to demonstrate compliance with FLSA wage and hour requirements. The law requires employers to maintain certain basic payroll and timekeeping records for covered employees.

Types of Records

Employers typically must track and retain information such as:

  • Employee’s full name and identifying information
  • Hours worked each day and total hours worked each workweek
  • Total daily or weekly straight-time earnings
  • Regular hourly rate of pay for any week when overtime is worked
  • Total overtime earnings for the workweek
  • Added pay for bonuses or other compensation that may affect the regular rate

Retention Periods

While specific retention rules can vary, guidance generally indicates that:

  • Payroll records, collective bargaining agreements, and related documents should be kept for at least three years
  • Supporting records used to determine wage computations, such as time cards or piece-work tickets, should be kept for around two years

Employers must also display an official Department of Labor poster summarizing the FLSA requirements in a conspicuous place, available from the WHD at no cost.

Special Topics: Youth Employment and Tipped Workers

The FLSA includes additional rules for certain categories of employees, including minors and workers who receive tips.

Youth Employment Standards

The FLSA aims to prevent oppressive child labor by limiting the type of work and hours that can be performed by minors.

  • Restrictions vary by age, with stricter rules for younger workers
  • Certain hazardous occupations are off-limits to minors
  • For older minors, there may be limits on the times of day and number of hours they can work

Tipped Employees

The FLSA allows specific treatment of employees who customarily receive tips. If an employee regularly earns more than a minimal amount in tips, the employer may count a portion of those tips toward the minimum wage, provided strict conditions are met.

However, if the combination of direct wages and tips does not equal at least the minimum wage rate, the employer must make up the difference to ensure compliance.

Compliance Strategies for Employers

Given the complexity of wage and hour rules, employers should adopt proactive strategies to minimize the risk of violations:

  • Conduct regular audits of employee classifications, pay practices, and timekeeping systems
  • Train supervisors on what counts as hours worked and the importance of approving and monitoring overtime
  • Implement clear policies about recording time, breaks, off-the-clock work, and remote work
  • Review state and local laws periodically to ensure the most protective standard is being applied
  • Consult legal or HR professionals when reorganizing job duties, restructuring pay, or implementing new scheduling systems

Strong compliance programs help protect employees’ rights and reduce the likelihood of back-pay liabilities, civil penalties, or litigation.

Frequently Asked Questions (FAQs)

1. Who enforces the FLSA?

The FLSA is enforced by the Wage and Hour Division of the U.S. Department of Labor. This agency investigates complaints, conducts compliance reviews, and may recover back wages and penalties on behalf of employees.

2. Does the FLSA require overtime pay for weekend or holiday work?

No. The FLSA does not require extra pay merely because work is performed on Saturdays, Sundays, holidays, or regular days of rest. Overtime is required only when total hours exceed 40 in a workweek.

3. Can employers average hours over two weeks to avoid paying overtime?

No. The FLSA applies overtime rules on a workweek basis. Employers cannot average hours over multiple workweeks to avoid paying overtime; each workweek stands alone for calculating overtime due.

4. Are salaried employees always exempt from overtime?

Not necessarily. Some salaried employees are nonexempt if they do not meet the specific duties and salary tests required for exemption. Those workers are still entitled to overtime pay when they work more than 40 hours in a workweek.

5. What happens if state law provides greater protections than the FLSA?

If state or local law offers higher minimum wage or more generous overtime protections than the FLSA, employers must follow the law that provides the most protective standard for the employee.
