Go on google and search for "employment lawyer near me". That will find you a decent employment lawyer.
Then you can have a talk with your managing director. You can tell him that you didn't expect the company in a shoddy way like that - the fact alone that you are aware that he is acting in a despicable way might change his mind. You can tell him that what he is doing is retaliatory, and any bigger company would have guidelines that forbid any retaliatory action in such cases. And finally you tell him that you talked to an employment lawyer (using one of the names that google showed you) and they would be willing to take your case if you are laid off.
