I am working in XXX for past 2 yrs and 11 months. I got a better job and I mailed my resignation letter on 26th September asking to be released by 25th October keeping the XXX policy of one month notice period in mind. But my project gave me 15th November as Release Date. Even my HR is telling he can release me only on the date given by my project. I'm fighting with one person or the other every day for my release date to be changed. My Date of joining in new company is 28th October and they told me they wont able to wait till 15th November and may cancel my call letter. I really dont know what to do and I feel my future career is in a big question mark. I seek your advice and help in this issue.
