CEVAP:

With the conclusion of an employment contract, the parties engage in a continuous contractual relationship and in this relationship, the labour of the employee, and hence his/her personality, is directly relevant in performance of obligations. Therefore, with a view to observe employee’s adaption to the work and the working environment, parties to an employment contract are free to insert a trial clause to the contract.

By doing so, the employer may see if the employee is fit for the position and the employee may see if the job is right for him/her.
