Dear Mr. Syedwasi,
If the company is shutting down; the company will pay you retrenchment compensation which will be equal to 15 days salary for every year of completed service. Besides, the employee needs to be paid with the notice period amount and other compensations made would be gratuity under The Payment of Gratuity Act (if the employee has completed 5 years of continued service) incase if the employer is covered under this act. Make sure of getting the full & final settlements and also withdraw PF by filling forms for signatures required from the HR department.
