Employment contracts in Poland must be in writing and signed no later than the day the employee begins work. If the employee does not understand the Polish language, the employer must provide a translation in a language the employee does understand. Employment contracts are generally for an indefinite term, a fixed term, or a trial period.
A contract for a trial period may not be for more than three months and may not be renewed outside of a few very specific situations. Contracts for a fixed term may be for a set time or until certain conditions are satisfied, such as the return of another employee from a temporary absence or the completion of specified tasks. If a fixed-term contract is for a set period of time, it may be renewed no more than two times, and all the contracts combined may not have a term longer than 33 months. If a fixed-term contract is renewed a third time, it automatically converts to a contract for an indefinite term.
At a minimum, the employment contract must state:
the identities of the parties,
the type of contract (indefinite, fixed-term, or trial period),
the date the contract is executed,
the workplace,
a description of the type of work,
salary details, and
working hours.
