One of the main provisions in shaping legal obligations between the parties is the freedom of contract. Although the parties are free to choose the provisions of their agreement, the content and the aim of the contract cannot contradict the essence and nature of the contract of employment, the act and the principles of the community life. Thereby, in order to engage an employee based on a long term contract of employment for a specified period, along with a short, two weeks notice termination period, justified and rational presumptions should be in place. In other words, taking into consideration current provisions of law, long term contract of employment is acceptable; however its validity is depended on the circumstances of each individual case.
