The school has given few employees two offer letters and taken them back within two aya of issuing. One states that notice period is one month and other states that notice period is three months only if you've been confirmed.. I joined school on 13th april and want confirmed as an employee as my probation was for one year.. Inspite of constancy reminders by all the staff they confirmed nobody and kept changing the principal and each time the principal changes the new rules came.
I resigned on 28th march and now they are asking me three months salary and are saying that they won't give my experience and relieving letter. I'm willing to serve my one months notice but they are forcing me to serve them till 14th august. How can there be a five months notice period?

They are making their own rules and harassing me by keeping my slary and not receiving me...

Kindly look into the matter and help
