I have been working with a CMM5 company for the last 2.5 months. As per my offer letter, an employee is on probation for 6 months before being confirmed. From the day of my joining, my manager made me work late nights and on weekends. The last 2.5 months have been without personal life, and it was a stressful period. Today, on 15th Feb 2017, I resigned, and I was told by HR that I have to serve a notice period of 30 days. I want to understand what I can do to get released as I don’t want to work here anymore. Kindly help.
