How do I get a valid medical sick leave document

Kindly note that, according to the Federal Labor Law, with regard to an application for a sick leave, it must be submitted to a medical committee whose report on the health condition must be recorded, and that the medical report should include a recommendation to grant rest for a specified period for the purposes of submitting it to the work authority, except for obtaining the leave and so that its value is not deducted.
Article 83

2. A worker who contracts illness after completing three months, following the probationary period, in the continuous service of an employer shall be entitled to a sick leave not exceeding 90 days, successive or otherwise, in respect of each year of service, to be calculated as follows.
• The first 15 days: with full pay.
• The next 30 days: with half pay.
• Any subsequent periods: without pay.
Article 84
No wage shall be payable for sick leave if the illness is the direct result of the worker's misconduct (such as consumption of alcohol or narcotic drugs).
Article 85
An employer may terminate the services of a worker who fails to report back to work after exhausting all sick leaves provided for in Articles 82, 83 and 84 hereof. In this case the worker shall be entitled to severance pay as stipulated in this Law.
