Wrongful Termination in Pennsylvania: Exceptions to At-Will Employment

Pennsylvania follows the at-will rule, which makes most firings lawful even when they seem unjust. Wrongful termination is the exception to that rule: a discharge that a statute, a contract, or a clear mandate of public policy makes illegal. This article explains what turns an ordinary firing into a wrongful one, the categories of exception Pennsylvania recognizes, and where a worker raises a claim. It is one of the procedures covered in Pennsylvania employment law, the plain-language reference to how work is regulated in the Commonwealth.

What “wrongful termination” means in Pennsylvania

At-will employment is the default in Pennsylvania. Absent an agreement to the contrary, either side can end the working relationship at any time, and the employer usually does not need a good reason. A firing that is unfair, poorly explained, or based on a manager’s personal dislike is generally still legal.

“Wrongful termination” is a narrower idea than “unfair firing.” A discharge becomes wrongful only when it crosses a legal line the law actually draws. Three broad categories draw those lines: statutes that forbid firing for a prohibited reason, contracts that replace at-will terms with defined ones, and a common-law public-policy exception that Pennsylvania courts apply cautiously. Everything the sections below describe fits into one of these three.

The public policy exception

Pennsylvania is one of the states whose courts recognize a public-policy exception to at-will employment. The exception is narrow. It applies only when a firing offends a clearly established mandate of public policy found in the state constitution, a statute, or a regulation, not a general sense of fairness. Courts have declined to expand it beyond well-defined situations.

The situations that most often qualify share a pattern: the worker was fired for doing something the law protects or encourages, or for refusing to do something the law forbids. Recognized examples include firing an employee for filing a workers’ compensation claim, for serving on a jury, for refusing to commit a crime the employer directed, or for reporting conduct that a statute requires be reported. In each, letting the firing stand would undercut a policy the state has already committed to in writing.

Separate from the common-law exception, Pennsylvania has a statutory protection for some whistleblowers. Under the Whistleblower Law, 43 P.S. § 1423, an employer may not discharge or retaliate against an employee who makes a good-faith report of wrongdoing or waste. That statute reaches public bodies and certain employers that receive public money, so it covers a smaller group than the general public-policy doctrine does.

Discrimination and retaliation: the statutory exceptions

The largest category of wrongful termination is a firing based on a protected characteristic. The Pennsylvania Human Relations Act makes it an unlawful discriminatory practice for an employer to discharge someone because of race, color, religious creed, ancestry, age, sex, national origin, or a non-job-related disability, under 43 P.S. § 955. The Act defines an “employer” to include anyone employing four or more people in the Commonwealth, and it protects workers age 40 and older, under 43 P.S. § 954. A 2025 amendment to that same section expanded “race” to include protective hairstyles and “religious creed” to include religious head coverings. The four-employee floor is lower than the threshold in most federal anti-discrimination laws, so a worker at a small Pennsylvania company may have a state claim where federal law does not apply.

Federal statutes overlap with the state Act and cover many Pennsylvania employers. Title VII, the Americans with Disabilities Act, and the Age Discrimination in Employment Act are enforced by the U.S. Equal Employment Opportunity Commission and generally reach larger employers.

Retaliation is its own form of unlawful discharge. It is illegal to fire a worker for opposing discrimination or for taking part in a discrimination proceeding, both under the state Act at 43 P.S. § 955 and under federal law at 42 U.S.C. § 2000e-3. A firing tied to protected family or medical leave is also prohibited: the Family and Medical Leave Act makes it unlawful for a covered employer to discharge a worker for exercising leave rights, under 29 U.S.C. § 2615. In a retaliation case, the reason for the firing, not the worker’s identity, is what makes it unlawful.

Contracts, unions, and handbooks

At-will status can be replaced by agreement. A written employment contract that promises a fixed term, or that allows termination only “for cause,” takes the relationship out of the at-will default and gives the worker a breach-of-contract claim if the employer fires without meeting the contract’s terms.

A collective bargaining agreement does the same thing for union-represented workers, typically requiring just cause for discipline and discharge and routing disputes through a grievance-and-arbitration process rather than a lawsuit. Public employees may have additional protections drawn from civil-service rules or constitutional due process.

Employee handbooks are a weaker source of protection. Pennsylvania courts treat a handbook as changing at-will status only in limited circumstances, and many handbooks include a disclaimer stating that they create no contract and that employment remains at-will. A general statement of progressive-discipline policy usually does not, on its own, override the at-will presumption.

How to challenge a firing you believe was unlawful

Where a claim goes depends on which exception applies. A discrimination or retaliation claim runs through an administrative agency before it can reach court. A contract claim is filed as a civil lawsuit. A common-law public-policy claim is also brought as a lawsuit, and courts allow it only where no statute already provides a remedy.

For discrimination and retaliation, the deadline is short and it is the single most important detail. A complaint under the Pennsylvania Human Relations Act must be filed with the Pennsylvania Human Relations Commission within 180 days of the firing, under 43 P.S. § 959. For claims that also fall under federal law, the EEOC allows up to 300 calendar days to file a charge in a state like Pennsylvania that has its own fair-employment agency, according to the EEOC’s time-limits guidance. The two agencies share charges through a work-sharing arrangement, but their deadlines and coverage thresholds are not identical.

1. Identify the legal basis for the claim

   Match the firing to an exception: a protected characteristic (discrimination), protected activity (retaliation), a contract or union agreement, or a clear public-policy violation. The category determines the forum and the deadline.

2. File with the right agency within the deadline

   Discrimination and retaliation claims start with an administrative charge. You file with the Pennsylvania Human Relations Commission within 180 days under 43 P.S. § 959, or cross-file with the EEOC within 300 days where federal law also applies, under the EEOC’s time-limits guidance. Contract claims skip this step and are filed directly in court.

3. Take part in the investigation

   The agency notifies the employer, gathers information from both sides, and may offer mediation or conciliation. Preserving pay records, the offer letter, any handbook, and written reasons given for the firing helps document the claim.

4. Move the case forward if it is not resolved

   If the agency does not resolve the matter, it can issue findings or a notice that clears the way to file a lawsuit. The administrative deadlines are what keep this option open, which is why the initial filing date matters so much.

A layoff or plant closing is not, by itself, wrongful termination. Losing a job for lack of work is generally lawful, and the rules that apply are advance-notice rules rather than the exceptions described here. Those requirements are covered in Pennsylvania’s WARN Act rules. A layoff can still become a wrongful termination if the selection for layoff was itself based on a protected characteristic or on retaliation.
