The law provide that an employee be in probation for three months before releasing him or her from the company. On many occasions an employee may need to issue a notice of contract termination, this depending on terms of contract. A fixed contract cannot be terminated unless a mutual agreement is reached by the two parties. Or the employer will have to pay the employee all the salary for the remaining period of time or at least salary for two months, depending on condition of termination.
According to: Article 75 of the Saudi Labor Laws (01/01/1437), In case of an undefined contract the employee is advised to issue a 60 or 30 days’ notice that should be effected in 30 days.
