Dear Santhu,
As you have mentioned that- PSU HR told that during probation period we will not give any noc ?
Please discuss with HR personnel to show it in writing if they have mentioned it anywhere.
If you will follow the exit procedure then they can't do like this.
I would suggest you to pls go through your appointment letter T&c.
