What a probationary contract is for
A probationary contract (umowa na okres próbny) exists to let an employer and a new employee assess whether the role and the working relationship are a good fit before committing to a longer arrangement. It is treated as a distinct contract category under the Labour Code, separate from fixed-term and indefinite contracts, and it is not counted toward the statutory limit on the number or duration of fixed-term contracts that can run between the same two parties.
The maximum length of a probationary contract is generally three months, although Polish law allows it to be shorter if the employer intends to follow it with a shorter fixed-term contract, in which case specific shorter caps of one or two months can apply depending on the planned total engagement length. Employers should decide the intended total employment picture before fixing the probation length, rather than defaulting to three months in every case.
The fixed-term contract limit: three contracts, 33 months
Outside of probation, Polish law limits fixed-term employment between the same employer and employee to a maximum of three contracts, with their combined duration not exceeding 33 months. This rule exists specifically to prevent employers from using repeated short-term contracts to avoid the stronger protections that come with indefinite employment, and it applies across contracts even if there are short gaps between them, subject to specific rules on what counts as a continuing sequence.
The practical consequence is that an employer cannot simply keep renewing a one-year fixed-term contract indefinitely. Once the fourth contract is signed, or the 33-month combined duration is exceeded, the law treats the employment relationship from that point as converted into a contract for an indefinite period -- regardless of what the paperwork says. This conversion happens automatically by operation of law, not as a discretionary penalty, which is why tracking contract history matters.
Permitted exceptions to the general limit
The Labour Code recognizes specific exceptions where the three-contract/33-month limit does not apply in the same way -- most notably contracts concluded to replace an employee during their justified absence (for example maternity or long-term sick leave), contracts for genuinely occasional or seasonal work, and contracts tied to a specific term of office. Employers relying on an exception should be able to justify why the particular situation genuinely fits the exception, because mislabeling an ordinary fixed-term role as a replacement contract to sidestep the limit is a known area of scrutiny.
Even where an exception applies, the employer must notify the relevant regional labour inspectorate of the basis relied upon, generally within a short period after signing the contract, in the cases the law specifically requires notification for. Skipping this notification does not necessarily invalidate the contract, but it removes a paper trail that would otherwise support the employer's position if the classification is later questioned.
Contract extensions and renewals in practice
A straightforward example: a business hires a marketing coordinator on a three-month probationary contract, followed by a one-year fixed-term contract, followed by a second one-year fixed-term contract. At this point two of the three permitted fixed-term contracts have been used, and 24 of the 33 permitted months have elapsed; a further renewal within the remaining nine months and the third-contract allowance is still possible, but a further renewal beyond either limit converts the relationship to indefinite-term employment automatically.
A second example involves a seasonal hospitality role genuinely tied to a tourist season each year: if the business can show the role is objectively seasonal, repeated fixed-term contracts across different years may fall under the seasonal-work exception rather than counting toward the general limit -- but this depends on the specific facts being genuinely seasonal, not merely convenient.
Notice periods during probation and fixed-term employment
Notice periods during a probationary contract are shorter than for longer engagements and are tied to the length of the probation itself -- broadly, the longer the agreed probation, the longer the notice period during it, up to a maximum of two weeks for a full three-month probation. This gives both sides a faster exit if the fit is clearly wrong, which is part of the probation's purpose.
Fixed-term contracts exceeding a certain length are, since reforms aligning their treatment with indefinite contracts, generally terminable on notice using periods linked to the employee's length of service with the employer, similar to indefinite contracts -- a change from the older position where many fixed-term contracts could not be terminated early on notice at all. Employers should not assume a fixed-term contract is automatically locked in for its full term without a notice option; the current notice-period rules should be checked for the specific contract length involved.
Practical examples by employment situation
A small business testing a new role for the first time might reasonably use the full three-month probation to evaluate performance before any longer commitment, especially where the role's requirements were not fully clear at the hiring stage. A business confident in the role and candidate, perhaps a rehire or an internal promotion, might choose a shorter probation or skip it in favor of moving straight to a fixed-term or indefinite contract.
A business covering a known, time-limited gap -- a project with a confirmed end date, or covering a colleague's parental leave -- is a natural fit for the replacement-contract exception, provided the paperwork genuinely reflects that purpose. Using the same exception to repeatedly avoid the general fixed-term limit for a role that is not actually temporary is the pattern most likely to draw scrutiny on inspection.
Keeping track so limits are not exceeded by accident
The practical risk in this area is rarely a deliberate attempt to evade the rules; it is simply losing track of how many fixed-term contracts a given employee has had and for how long, especially across HR system changes or staff turnover in the HR function itself. A simple register -- employee name, contract type, start and end dates, and a running total of fixed-term months and contract count -- avoids the conversion surprise entirely.
If your business already has employees approaching or past the three-contract or 33-month marks, it is worth reviewing those records now rather than at the next renewal date. Auranik's 1 Point Business Service Package (/poland/consulting/business-services) can help organize employee contract-history tracking alongside your HR team, while any specific reclassification question should be confirmed with a qualified employment-law advisor.
