A Warsaw-based software company signs a post-employment non-compete agreement with its lead developer. Eighteen months later, the developer joins a direct competitor. The company's legal team discovers the agreement omitted the compensation clause required under Polish labour law. The clause is unenforceable. The trade secrets walk out the door, and the company has no contractual remedy.

Non-compete clauses in Poland are governed by the Kodeks pracy (Labour Code, KC) and, for civil-law contracts, by the Kodeks cywilny (Civil Code). A post-employment restraint is enforceable only if it is in writing, defines the scope of prohibited activity, specifies a duration, and provides compensation of at least 25% of the employee's prior remuneration for each month of the restriction. Clauses that omit any of these elements are void and provide no protection.

This guide walks through the legal framework step by step: how to draft a valid clause, what compensation is required, which mistakes render the agreement unenforceable, how courts assess scope and duration, and what employers and employees should do when a dispute arises. Three business scenarios illustrate the rules in practice.

What does Polish law require for a valid non-compete clause?

Polish labour law distinguishes two types of restraint. The first operates during employment and may prohibit the employee from any competing activity for the duration of the contract. The second – the post-employment non-compete – applies after the employment relationship ends and carries stricter formal requirements. Both must be concluded in writing as a separate agreement; a clause buried in the employment contract body is permissible but must still satisfy all formal conditions. The National Labour Inspectorate (Państwowa Inspekcja Pracy, PIP) regularly flags informally drafted clauses during workplace audits.

For a post-employment clause to be enforceable, four elements must appear in the written agreement. First, the scope of prohibited activity must be defined with sufficient precision – naming the industry, type of client, or category of product. Second, the geographic scope should reflect the employer's actual market. Third, the duration must be stated; Polish courts have refused to enforce open-ended clauses. Fourth, the compensation obligation must be explicit: at least 25% of remuneration received in the corresponding period before the end of employment. Missing even one element allows a court to strike the clause entirely.

The employer also bears the burden of proving that the employee had access to "particularly important information" (szczególnie ważne informacje) whose disclosure could harm the employer. This threshold matters. Courts applying Labour Code provisions have repeatedly held that a generic reference to "confidential business information" is insufficient. The agreement must identify, at least in general terms, what protected knowledge the employee possesses. A 30-day review of this threshold at the drafting stage prevents costly litigation later.

  • Written form – mandatory; oral agreements are void
  • Defined scope – industry, product, or client category
  • Fixed duration – no open-ended restraints
  • Compensation – minimum 25% of prior monthly remuneration
  • Protected knowledge – employer must identify the interest being protected

How is compensation calculated and paid?

The 25% floor is a statutory minimum, not a market rate. It is calculated against the employee's average monthly remuneration from the period immediately before the end of employment. For a developer earning PLN 20,000 per month, the minimum monthly compensation during a 12-month restraint is PLN 5,000 – totalling PLN 60,000 over the full period. Many employers offer higher rates (typically 50–100%) to reduce the risk of a court reducing the restraint period on proportionality grounds.

Compensation must be paid in instalments corresponding to the restraint period – monthly in practice. An employer who stops paying forfeits the right to enforce the clause. This is one of the most common mistakes in post-employment disputes: the employer ceases monthly payments after a few months, believing the employee has already found work elsewhere, and then attempts to enforce the clause when the employee joins a competitor. Polish courts treat non-payment as releasing the employee from the obligation. The release is automatic and irreversible once payment has lapsed.

We secured a reversal of a penalty claim exceeding PLN 180,000 for a manufacturing client in the Mazowieckie region (autumn 2025). The employer had withheld compensation for three consecutive months, believing the clause remained enforceable because the employee had not formally objected. The court held that the restraint had lapsed by operation of law.

For employers with a mixed workforce – some on employment contracts, others on B2B or civil-law mandates – the compensation rules differ. Civil Code contracts are not subject to the 25% statutory floor. However, courts applying general civil-law principles will assess whether the restraint is proportionate. An unpaid post-contractual non-compete in a B2B arrangement may be reduced or voided under the general clause on abuse of rights.

What scope and duration will courts enforce?

Duration is assessed against the legitimate interest being protected. Polish courts have generally upheld restraints of 6 to 24 months for senior employees with access to strategic information. Restraints exceeding 24 months face heightened scrutiny; the Supreme Court of Poland has signalled that very long clauses may be reduced to a reasonable period rather than struck entirely. A 12-month restraint is the most commonly enforced benchmark in Warsaw employment litigation.

Geographic scope must match the employer's actual market. A clause covering "the entire world" for a domestic SME will likely be narrowed by a court to Poland or the relevant region. For multinationals with genuinely international operations, a broader scope is defensible – but the agreement must contain evidence of that operational reach. Cross-border employers (for example, those covered by our analysis of employment law compliance for Netherlands companies in Poland) should tailor scope to each jurisdiction separately.

Activity scope must also be specific. A blanket prohibition on "any competing activity" has been reduced by courts to the employee's actual area of work. An IT architect restrained from "any activity in the technology sector" achieved a judicial reduction to software architecture roles only – the broader prohibition was disproportionate. Drafting tip: list the specific roles, clients, or product lines that represent the genuine risk, rather than describing entire industries.

For employers managing industrial operations with environmental or regulatory exposure, the same proportionality logic applies across legal instruments – see our note on environmental liability for industrial operations in Poland for a parallel example of how Polish courts calibrate statutory obligations to actual risk.

A concrete bridge: if the employer can show that the employee had access to a client list representing 40% of annual revenue, a 12-month restraint covering that client category and a defined geographic region will typically survive judicial review. Judges in Warsaw and Kraków district courts apply this proportionality test consistently.

What are the most common mistakes – and how to avoid them?

Three scenarios illustrate recurring errors. First: a Kraków-based IT firm engaged a senior project manager on a B2B contract. The post-contractual non-compete prohibited any work for competitors for 18 months. No compensation was specified. When the manager joined a rival firm, the IT company sought an injunction. The court dismissed the claim. An unpaid civil-law non-compete with no proportionality justification is unenforceable under general contract principles. The firm lost 18 months of protection it believed it had purchased.

Second: a German investor's Polish subsidiary (Lower Silesia, spring 2026) included a non-compete clause in its standard German-language employment contract template. The clause was not translated, and the Polish-law compensation requirement was not addressed. Polish employees are protected by mandatory provisions of the Labour Code regardless of the contract language. The clause failed on both the language and compensation grounds. Our team obtained a full restructure of the subsidiary's template contracts before the matter reached litigation.

Third: a Warsaw logistics company enforced a non-compete against a warehouse supervisor. The court found that the supervisor had no access to "particularly important information" – his role involved operational execution, not strategic or commercial data. The employer had applied a standard senior-employee template to a mid-level operational role. The clause was void from inception. Employers should calibrate clause type to actual seniority and access level, not apply one template across all roles.

Foreign investors entering Poland through Spanish or other EU structures face the same mandatory-law constraints. Our guide on employment law compliance for Spain companies in Poland addresses how EU parent-company templates interact with Polish Labour Code requirements.

What to prepare when drafting a non-compete agreement:

  • Role description confirming access to protected information
  • Written agreement separate from (or clearly identified within) the employment contract
  • Defined scope: activity type, client categories, geographic region
  • Compensation schedule with monthly payment dates and amounts
  • Internal procedure for monitoring payment obligations during the restraint period

The risk is not just losing a court case. An unenforceable non-compete forfeits the employer's ability to prevent a key employee from moving to a direct competitor – sometimes permanently, if the limitation period for the underlying trade-secret claim has also lapsed. That lost opportunity cannot be recovered after the fact.

Frequently asked questions

Q: Can an employer release an employee from a post-employment non-compete before the restraint period expires?

A: Polish Labour Code provisions allow the employer to release the employee from the obligation – but the release also terminates the employer's compensation obligation only if the agreement expressly provides for this. If the agreement is silent, courts have held that releasing the employee from the restraint does not automatically release the employer from paying compensation already accrued. Employers should include an explicit mutual-release clause to avoid this outcome.

Q: How long does an employee have to bring a claim for unpaid non-compete compensation?

A: Employment-related monetary claims in Poland are subject to a three-year limitation period running from the date each instalment became due. An employee who was not paid monthly compensation for a 12-month restraint may bring a claim for the full amount up to three years after the last unpaid instalment. The clock runs separately for each monthly payment, so partial claims are possible even if earlier instalments have become time-barred.

Q: Does a non-compete clause prevent an employee from working on a B2B basis for the same competitor?

A: A properly drafted clause covering "any form of competitive activity" – including services provided through a sole-trader registration or a company – will extend to B2B arrangements. However, the clause must explicitly describe the prohibited conduct in terms broad enough to cover indirect competition. A clause that refers only to "employment" with a competitor will not prevent the same individual from providing services through a separate legal entity. Precise drafting of the activity scope is the key safeguard.
