thank you for your answers

yes it is stated in our contract that they will provide the air ticket and would cover the total cost but in reality they limited the cost until 1000 qar which is not stated in the contract.

about the gratuity, it wasn't stated on the contract, that is our most problem here. One of my colleague almost didn't get anything from her 3 years of service, but she fought and reached out to the labor, and when the labor called our employer, he was very furious and treated my colleague like a criminal and sent her out of the company right away without any formality, and spread bad rumors about her. -_-

I just wish all employers aren't like this.

As for the certificate, we will fight for it cause it is the only document that we can carry out after leaving the company.
