Important Changes in U.S. Labor Laws

5 Important Historical Changes to U.S. Labor Laws

Employment laws have evolved significantly as lawmakers, federal agencies, and courts have addressed wages, workplace safety, hiring practices, and employee protections.

Understanding these historical developments helps employers recognize why workplace compliance requirements continue to change.

Below are five important developments in U.S. labor law history and their significance for employers. This article provides historical context rather than current wage rates, penalty amounts, or legal requirements.

1. Minimum Wage Protections for Federal Contractors

In 2014, President Barack Obama signed Executive Order 13658, establishing a minimum wage requirement for workers performing on or in connection with certain covered federal contracts.

The initial minimum wage was $10.10 per hour beginning January 1, 2015. The rate increased to $10.15 per hour in 2016, with separate requirements for covered tipped employees.

The executive order represented an important development in federal contractor wage protections.

Subsequent administrations introduced additional changes to federal contractor minimum wage requirements, including Executive Order 14026 in 2021 and its revocation in 2025.

Employers performing federal contracts should review current Department of Labor guidance and applicable contract provisions rather than relying on historical wage amounts.

2. Changes to Federal Overtime Regulations

The Fair Labor Standards Act (FLSA) establishes federal minimum wage, overtime, recordkeeping, and youth employment standards for covered employment.

In 2016, the U.S. Department of Labor issued a rule intended to increase the salary threshold for certain executive, administrative, and professional overtime exemptions.

The rule would have increased the standard salary threshold to $913 per week, or $47,476 annually.

However, a federal court blocked the rule before it took effect, and the rule was subsequently invalidated.

Later administrations introduced additional overtime regulations, some of which also faced legal challenges.

This history illustrates why employers must review both applicable salary thresholds and job-duty requirements when evaluating overtime exemptions.

3. Federal Fair-Chance Hiring Protections

Fair-chance hiring initiatives, commonly known as "Ban the Box" policies, developed across numerous states and local jurisdictions to limit when employers may inquire about an applicant's criminal history.

The federal Fair Chance to Compete for Jobs Act was enacted in December 2019 as part of the National Defense Authorization Act for Fiscal Year 2020.

Its principal hiring restrictions took effect in December 2021.

The law generally restricts federal agencies and certain federal contractors from requesting criminal history information before making a conditional employment offer, subject to statutory exceptions.

State and local fair-chance hiring requirements may differ from federal requirements.

Employers should review the laws applicable to their locations and hiring practices.

4. Increases in OSHA Civil Penalties

The Occupational Safety and Health Administration (OSHA) enforces federal workplace safety and health standards for covered employers.

In 2016, federal OSHA civil penalties increased substantially following legislation requiring inflation adjustments.

The initial adjustment was significant because maximum penalties had remained largely unchanged for many years.

OSHA penalties are subject to subsequent adjustments, and applicable amounts depend on the violation classification and governing requirements.

Employers should review current official penalty schedules rather than relying on historical figures.

Workplace safety compliance also involves maintaining appropriate safety procedures, providing required training, and displaying applicable notices.

5. The Pregnant Workers Fairness Act

The Pregnant Workers Fairness Act (PWFA) represents a significant development in federal workplace protections for employees affected by pregnancy, childbirth, and related medical conditions.

Congress enacted the PWFA in December 2022, and the law took effect on June 27, 2023.

The PWFA generally requires covered employers to provide reasonable accommodations for known limitations related to pregnancy, childbirth, or related medical conditions unless doing so would impose an undue hardship.

The law operates alongside existing federal protections, including Title VII of the Civil Rights Act of 1964, as amended by the Pregnancy Discrimination Act.

Employers should review current Equal Employment Opportunity Commission guidance and applicable state laws when developing accommodation policies.

Why Labor Law Changes Matter to Employers

These historical developments demonstrate that employment compliance is not static.

Federal regulations, state legislation, local ordinances, court decisions, and administrative actions can all affect workplace obligations.

Employers should regularly review applicable requirements involving wages, employee rights, workplace safety, hiring practices, and mandatory notices.

How Employers Can Maintain Workplace Posting Compliance

Many federal, state, and local employment laws require covered employers to display notices explaining employee rights and employer responsibilities.

Posting requirements vary depending on workforce size, industry, geographic location, and other applicable legal conditions.
