The employer is not paying the salary on time. What can the employee do?

Hello Madam,

My company is not paying salary on time. I have a pending of one and a half months. Whenever I ask for the salary, they do not respond to my emails and messages. Every two months only they pay me.

Through the MOHRE App, the WPS section is empty. I'm not able to monitor my salaries. And I have a fear of getting all the money at the end of my service because my colleagues suffered a lot for getting payment from the company. They didn't get paid fully.

How to handle this matter?

Furthermore, my employer is holding my passport too. They informed me that they will provide it in case of vacation or resignation. What to do on this matter too?
