US Termination Laws: At-Will vs. Just Cause

In the US, there are two main ways to fire an employee: at-will and just cause. Knowing
the difference between these two types of termination is important because they affect employees’ rights and why
they were fired. 

The table below summarizes the key differences between at-will and just-cause employment
in the US, its implications on employers and employees, and the legal considerations in each scenario.

Key Differences Between At-Will and Just-Cause Employment


At-Will Employment

Just Cause Employment

What is it?

  • Either employer or
    employee can terminate an employment contract can terminate at any time, for any reason
    (or no reason), without notice or legal liability, unless unlawful.
  • Provides limited
    protections as employees can be terminated without cause unless exceptions apply.
  • Employers must
    provide a valid, documented reason for termination, usually related to misconduct, poor
    performance, or business needs.
  • Commonly practiced
    in unionized workplaces, government positions, or employment contracts.
  • Offers greater
    protections to workers as employers must justify termination with documented
    reasons.
  • Montana is the only
    state that requires just cause for terminating employees after a probationary
    period.

Applicability

  • The default
    employment framework applied to most private-sector employees in all US states except
    Montana. 
  • Public-sector
    employees may be excluded.
  • Workers employed
    under a signed contract with custom employment agreements or employees covered by a
    union’s collective bargaining agreement may have specific termination terms.
  • Applies primarily
    to employees in Montana where just justified reasons for termination are required after
    the employee’s probationary period ends.

Exceptions 

  • Public Policy Exception: Employees cannot be terminated for reasons that violate public
    policy, like reporting illegal activity.
  • Implied Contract Exception: Some state courts in the U.S. recognize implied contracts
    through employer statements and practices.
  • Covenant of Good Faith and Fair Dealing:
    In some states, employers cannot fire employees in bad
    faith or for malicious purposes.
  • Federal Protections: State and federal laws prohibit termination due to
    discrimination and retaliation.
  • Union Contracts: Employees covered by collective bargaining agreements may have
    additional rights, requiring employers to follow certain procedures outlined in the
    contract before terminating an employee. 
  • Public Sector Jobs: Civil service laws often require adherence to specific
    processes before termination in public sector roles.
  • Contractual Provisions: Employment contracts may outline specific grounds and
    procedures for termination that an employer must follow.
  • Federal Protections: Federal anti-discrimination laws and retaliation protections
    apply to just cause employment to prevent unfair terminations.

Termination Reasons

  • No reason is
    required as long as it is not illegal. 
  • Termination must be
    based on valid reasons, such as misconduct, poor performance, or violation of company
    policies.

Advance Notice Requirements

  • No advance notice
    is required unless specified in a contract or by state law.
  • Requires documented
    performance issues. 
  • Often follows a due
    process involving warnings and evaluations before termination.

Legal Protections

  • Title VII of the Civil Rights Act of 1964: Title VII of the Civil Rights prohibits workplace discrimination and protects employees
    from termination based on race, color, age, sex, national origin, or religion.
  • Age Discrimination in Employment Act (ADEA): The
    ADEA protects
    employees aged 40 or older from being fired due to age discrimination. 
  • Americans with Disabilities Act (ADA): Under the
    ADA, employees
    cannot be terminated due to physical disability and for requesting or needing
    accommodations to perform essential functions of their job (unless it causes undue
    hardship to the employer).
  • Family and Medical Leave Act (FMLA): The FMLA protects
    employees from being retaliated against or terminated for taking protected leave.
  • Worker and Adjustment and Retraining Notification (WARN) Act: The WARN Act
    requires employers with 100 or more employees to provide 60 days’ notice before
    large-scale layoffs or plant closures. 
  • Occupational Safety and Health Act (OSH Act): OSHA prohibits employers from firing employees in retaliation for
    reporting workplace safety violations or refusal to work under unsafe conditions.
  • The Wrongful Discharge from Employment Act (WDEA) provides legal
    protections against unjust termination for employees in Montana.
  • Employees cannot be
    discharged in retaliation for refusing to participate in illegal activities, reporting a
    violation of public policy, or for the employee’s freedom of speech, including
    statements on social media.
  • WDEA does not
    protect employees during the probation period. 
  • During probation,
    either party may end employment at will, for any or no reason.

Filing Wrongful Termination Claims

  • Wrongful termination claims must be filed with federal or
    state agencies within 180 to 300 days after termination.
  • Employees
    terminated based on discrimination or retaliation can file a claim with the
    Equal Employment Opportunity Commission (EEOC).
  • Employees (except
    for USPS and public-sector employees) wrongfully fired for reporting safety violations
    or exercising rights under federal safety laws can file a claim
     under OSHA whistleblower programs.
  • If applicable,
    employees can also file a wrongful termination claim with their state’s labor or human
    rights agency. 
    • Claims may be filed
      if terminations violate the terms of employment contracts or collective bargaining
      agreements.
    • If an employee in
      Montana believes they were wrongfully terminated without cause, they can file a claim
      with the
      Montana Department of Labor and Industry within one year of termination.
