Is my sponsor (the recruiter) supposed to pay for my return flight?

If you leave within the 3 month probation period you are expected to pay the home bound flight.

   PROBATIONARY PERIOD
• If the worker is subject to a probationary period, the employment contract will expressly state and clearly specify that the worker be under probation, so that it does not exceed ninety days. A written agreement between the worker and the employer may extend the probationary period, if it does not exceed one hundred and eighty days. Eid Al-Fitr, Eid Al- Adha and sick leave are not included in the probationary period. Each of the parties has the right to terminate the contract during this period unless the contract contains a text that gives one of them the right to terminate the contract.
• Eid Al-Fitr and Eid Al-Adha holidays and sick leave are not included in the probationary period.
• A worker will not be employed under probation more than once by one employer. Excluded from hereto, by a written agreement between the parties of the contract, the worker may be subjected to another probationary period provided that:
To be in or another the worker’s relationship with the employer has another job work ended for a period of no less than six months
• If the contract expires during the Probationary period, both parties do not deserve compensation, and the worker does not deserve an end-of-service pay.

Thank you for your response.
