The Regime of Fixed-Term Employment Contracts
An employment contract is concluded orally or in writing, for a fixed or indefinite term. Where the duration of the employment relationship exceeds 1 month, written form is mandatory. Conclusion for a fixed term is, as a rule, permissible only on a closed list of grounds — the legislator's response to the abusive use of term contracts. In other words: the rule is an open-ended contract, and the exception is a fixed term.
An employer choosing a fixed term must justify that choice by a ground provided by law. Otherwise the contract is deemed concluded for an indefinite term — an automatic consequence that does not depend on the parties' agreement. This makes the existence of a statutory ground the central question of every dispute over term contracts.
