I worked at a consultancy firm in Meghalaya (which has its main office in Kolkata) for 3 months (December to February) after which i was fired citing poor performance. The probation period itself was 3 months so once my work was over, i was formally called over to work in Kolkata. Please note that my probation period was spent in Meghalaya. i was supposed to start on 20th March at the kolkata office and left Meghalaya on 3rd march via flight. On 5th march, the HR along with my two managers did a sudden performance review where both my managers falsely accused me of consuming narcotics in Meghalaya, sharing company documents to other stakeholders, harassing a female collogue and risking the safety of my teammates. Subsequently, HR told me to resign citing poor performance. I refused and filed a complaint with the Disciplinary action committee (DAC) the very next day against the manager who made the allegations. 3 days later, the DAC published an order saying that the managers had failed to provide any proof for the allegations and subsequently asked him to apologize formally, which he did via mail. A day later HR calls me up and says that she has read the DAC order but would still not want to work with me as upper management is not satisfied with my performance. When i refused, i was handed a termination letter on the same day.
what should i do in this scenario? what options do i have should i approach the labour court, considering this is a private firm we are talking about?
