Salary held by employer

Hello,

I need help of members here.

I resigned my school on health grounds. Could not serve notice period nor the offer letter has any mention of notice period.

I was 10 days away from my salary day.

School did not pay my salary

They are not returning my original certificates

They are not returning post dated cheques.

What is the remedy? Can I lodge FIR at the Police station if yes under what sections.

Regards
