According to my offer letter from my employer, my notice period is 3 months. If I want to leave without giving a 3-month notice, already 10 days' salary has been paid to my employer as per our settlement. But now, he wants me to sign on some stamp paper for an R and E certificate. According to the stamp paper, he said, "Don't work with any other company engaged in similar businesses for 24 months from relieving." I have no need for an R & E certificate for the next job.
