Overview of the US Labour Law System
The U.S. does not have a singular labour code. Instead, its labour law system is built upon a network of federal laws supplemented by state and local regulations. Key statutes include the Fair Labor Standards Act (FLSA), Title VII of the Civil Rights Act, the Family and Medical Leave Act (FMLA), and the Occupational Safety and Health Act (OSHA).
Employers must understand how these layers interact and ensure their policies meet the most stringent applicable standards. Staying updated on changes at both federal and state levels is essential for long-term compliance.
Federal vs State Employment Laws
Key Federal Employment Statutes
Federal labour laws establish the baseline protections for all U.S. workers. The most influential statutes include:
- FLSA: Regulates minimum wage, overtime pay, and child labor
- Title VII: Prohibits employment discrimination based on protected characteristics
- ADA: Ensures equal access and accommodations for individuals with disabilities
- FMLA: Grants up to 12 weeks of unpaid leave for qualified family and medical reasons
- NLRA: Protects workers’ rights to unionize and engage in collective bargaining
These federal laws are enforced by agencies like the Department of Labor (DOL), Equal Employment Opportunity Commission (EEOC), and National Labor Relations Board (NLRB).
State-Level Variations and Preemption
States often expand upon federal protections. For example, California mandates higher minimum wages, paid sick leave, and broader anti-discrimination rules. New York, Massachusetts, and Washington also lead in enacting progressive labour laws. When state law conflicts with federal law, the law that offers greater employee protection generally prevails.
Employers operating in multiple states must adapt policies and payroll practices accordingly.
Employee Classification and Worker Rights
Properly classifying workers as employees vs. independent contractors, and exempt vs. non-exempt, is critical. Misclassification can lead to unpaid wage claims, penalties, and IRS audits. Exempt employees are not entitled to overtime; non-exempt employees are.
Key tests like the IRS Common Law Test and ABC Test (used in states like California) help determine classification. Employers must also be mindful of gig economy trends and how evolving legal interpretations affect rights such as benefits and unemployment insurance.
Minimum Wage and Overtime Laws
The federal minimum wage remains $7.25 per hour as of 2025, though many states and cities have enacted higher rates. Employers must always follow the higher applicable minimum.
Under FLSA:
- Non-exempt workers must receive 1.5x pay for hours worked over 40/week
- Exemptions apply based on salary thresholds and job duties (e.g., executive, administrative roles)
Employers must also be aware of “wage theft” risks and ensure accurate timekeeping and payroll records.

Working Hours, Rest Breaks, and Meal Periods
Federal law does not mandate breaks, but many states do. For instance:
- California requires a 30-minute unpaid meal break after 5 hours and 10-minute rest breaks every 4 hours
- Colorado, Oregon, and Illinois have similar regulations
Employers must track hours accurately for wage compliance and avoid forced off-the-clock work. Flexible scheduling laws in some states also require advance notice before shift changes.
Statutory Leave and Time-Off Policies
The Family and Medical Leave Act (FMLA) entitles eligible employees to up to 12 weeks of unpaid, job-protected leave for reasons like childbirth, personal illness, or caring for a family member.
Some states provide paid family leave, including:
- California
- New York
- Washington
- Massachusetts
Paid sick leave laws are increasingly common at the state and municipal level. Employers should draft leave policies that reflect both federal and local obligations.
Anti-Discrimination and Equal Employment Laws
Federal laws enforced by the Equal Employment Opportunity Commission (EEOC) prohibit discrimination based on:
- Race, color, national origin
- Religion
- Sex, gender identity, and sexual orientation
- Age (40+)
- Disability
- Pregnancy
Employers must maintain inclusive hiring practices, provide reasonable accommodations, and respond to harassment complaints. Internal reporting channels and anti-bias training are essential for a compliant and respectful workplace.
Health and Safety Regulations
The Occupational Safety and Health Administration (OSHA) sets federal standards for workplace safety. Employers are required to:
- Identify and mitigate workplace hazards
- Maintain injury logs
- Provide personal protective equipment (PPE)
- Train employees on safety procedures
Some states operate their own OSHA-approved programs with more stringent rules. Remote and hybrid workers must also be supported with safe and ergonomic working environments.
Termination Rules and At-Will Employment
The U.S. follows the at-will employment doctrine, which allows either party to terminate the relationship at any time without cause. However, exceptions include:
- Termination based on discrimination or retaliation
- Violations of public policy
- Breach of contract
Providing written termination procedures, final paycheck guidelines, and optional severance policies can help mitigate risks and avoid wrongful termination claims.
Employment Contracts and Offer Letters
While not always required, well-drafted employment contracts protect both parties. These often include:
- Compensation and benefits
- Confidentiality clauses
- Non-compete and non-solicitation agreements
- Dispute resolution processes (e.g., arbitration)
Offer letters should clearly outline job duties, expectations, employment status, and termination terms to prevent ambiguity and miscommunication.
Immigration and Work Authorization Compliance
Employers must verify every new hire’s identity and work authorization via Form I-9. In some states, use of E-Verify is mandatory.
Penalties for non-compliance include fines, reputational damage, and potential debarment from federal contracts. Regular I-9 audits and employee re-verifications are recommended best practices.
Employer Responsibilities for Payroll and Benefits
Employers must:
- Withhold federal income tax, Social Security, and Medicare (FICA) contributions
- Pay unemployment insurance (FUTA and state-level)
- Administer benefits like health insurance and retirement plans (where applicable)
Many of these responsibilities are regulated under ERISA, COBRA, and the Affordable Care Act (ACA). Transparency in deductions, timely reporting, and employee communication are essential.
Using an Employer of Record (EOR) in the USA
Global companies without a U.S. entity can partner with an Employer of Record (EOR) to compliantly hire American workers. An EOR handles:
- Local onboarding and contracts
- Payroll, taxes, and benefits administration
- Compliance with wage, leave, and termination laws
Asanify, for example, offers EOR services that simplify U.S. hiring while ensuring full legal compliance. This is especially useful for startups and remote-first teams expanding across state lines.
Compliance Tips for Employers in 2025
To stay compliant in 2025:
- Review federal, state, and local laws regularly
- Audit employee classifications and contracts
- Keep payroll, leave, and termination records accurate
- Train HR and managers on evolving regulations
- Work with employment lawyers or EOR providers when expanding or restructuring
Being proactive about compliance not only protects your business legally but also builds employee trust and brand reputation. Leveraging digital HR tools and legal guidance ensures fewer surprises and better long-term outcomes.
