Does my employment contract automatically renew if there is no expiration date?
Generally, an employment contract which doesn't specify an expiration date continues indefinitely until terminated by a party giving notice. It is possible to have an employment contract for both an indefinite and definite period of time. An employment contract which is for an indefinite period is terminated by giving notice to the other contracting party. The normal employment contract of indefinite duration continues to take effect until it ends in the circumstances laid down by law.
Automatic renewal clauses are typically for contracts of a certain duration, such as a yearly lease, and must be included in the contract. The severance clause in an employment contract of indefinite duration will remain in effect until the contract is terminated. The date of signing the agreement will remain the same unless the contract specifies otherwise.
