I am working at IT company @chennai. My probation period was 6 months and as per HR document/ offer letter that they mentioned probation period notice period was 7 days post probation it was 30days. But yesterday my manager asked me to serve 2months of notice period I ask why I have to serve 2months of notice since my official notice period was 7 days? still he insist me to serve 2 complete month notice period. please suggest what should I do now?
