I have accepted a offer with a new company.
After my last debacle, I have thoroughly discussed with the new employer their technology stack, their work culture, their future timelines and my capabilities and interest areas. After much discussion, I decided to join this company and having accepted their offer, I informed my manager.
As soon I started my conversation, he seemed to be highly pissed off. He started trying me to stay by emotionally blackmailing me by saying I'll be hampering his reputation, etc.
He promised me that he will move me to another project which utilizes my skill-set, but what I have seen there are hardly any project being build in my tech stack.
Since we both belong to same geographical area and can speak same language, some of his words spoken in our native tongue can be taken in multiple different meanings, some of which were threatening in nature.
I'm a bit scared that he might sabotage my references and other chances in future since he is more than 20 yrs of experience and has a lot of contacts in the technical domain. How do I handle this situation?
