I got an offer for a better position in another company. However i need to join in a weeks time. I send a mail stating ill serve a notice period of 8 days. My manager says its cant be. I give the option of buyout(pay penalty etc.) and/or resignation against leave balance (have 30 days balance). Still my manager says i cant leave before 30 days, but in 30 days ill loose the new job offer. I have been told ill not be given my relieving/experience letter if i leave in 8 days and if i leave and not come after 8 days hell take me as absconding. What can i do in this case?
