I am an employee of a company for the past six years, you have resigned from my company and served the notice period. However my company head does not want me to leave and delay every process even work handover and now the notice period is completed, he is still telling me that I didn't complete the project and didn't do proper handover. At the same time companies, and the legal team threatened to file a case against me and will demand all the money given to me because it is investors' money and what projects I have done is not worthy enough and acceptable to them. They are also blaming to founder/CEO for this. I don't know whether this is a game against me to retain me. Please advise that in which case the company can file this kind of case against an employee.
