We would like to inform you that according to the Omani Labor Law, states that the termination without notice or legal reason is considered arbitrary dismissal and the employer shall pay compensation to the worker as the below article states:
Article 106:
An employee who has been dismissed from work may apply to the concerned Directorate within 15 days from the date he has been notified of the dismissal of his notice, to cancel the decision of dismissal. The concerned authority shall take the necessary measures to settle the dispute amicably. The directorate must reduce it to writing and follow up its execution. If the employer refuses to execute the agreed settlement, he shall be obliged to pay an amount equivalent to the employee's salary for the period from the date of settlement until the date he executes the same. If the dispute is not settled within two weeks, or if settled and any of the parties refuse to execute it, the concerned authority shall refer the matter to the competent court within a period not exceeding two weeks from the date of the expiry of the aforesaid period or from the date of the refusal to execute it, together with a memorandum containing a summary of the dispute and the parties' arguments.
The Secretariat of the court shall, within three days from the date the matter is referred to the court, present the same to the president of the court to fix a date for a hearing within a period not exceeding two weeks from the date of referral. A summons for the date of hearing, with enclosed copy of the said Directorate memorandum, shall be served on the employee, the employer and the concerned Directorate. The court shall make a decision in respect of the application for staying the execution of such dismissal, if any, within a period not exceeding two weeks from the date of the first hearing session and the court judgment shall be final. If the court decides to stop the enforcement of the dismissal, the employer shall be bound to reinstate the employee or to pay him an amount equal to his salary until the subject matter of the dispute is adjudicated. The court shall pass its judgment on the dispute within a period not exceeding one month from the date the enforcement of the dismissal is stayed.
If it is proved to the court that the dismissal of the employee or the termination of his services was arbitrary or contrary to the Law, it may decide to either reinstate the employee or oblige the employer to pay him fair compensation in addition to:
The end of service gratuity to which the employee is lawfully entitled and all other benefits prescribed by the law or the contract of employment, whichever is greater.
The basic salary together with the other allowances, if any, for the notice period provided for by the Law or the contract of employment, whichever is greater.
The amounts which the employee may have received in execution of the judgment, shall be deducted from the compensation amount awarded to the employee or from any other amounts due to him.

The complaint can be submitted before the labor office, as it is the competent authority, and for violating the provisions of the Labor Law, since it has the jurisdiction to end the labor dispute, and it is the one who obliges the employer to the work contract, otherwise it is considered an arbitrary dismissal

Dear, it is not valued by the employer, as long as the leave has been completed and the specified period for it has expired. It is not permissible to extend it or force the worker to take a long leave, and this is against the law.

Dear, submitting a complaint is the correct legal procedure with a statement refusing to hand you over the work for the purposes of legal processing with the knowledge of this body
