I accepted an agreement with my educational institution for five years, in which the salary is mentioned only for one year. Later, it can be revised. Due to a health problem, I resigned from my job after completing only four months, as I am suffering from spinal cord compression. They are asking for compensation for the four months' salary. They didn't provide me with any training. Before signing the agreement, I had already worked there for two years. However, they have not provided a copy of the agreement, appointment order, or ID card. If I pursue legal action, how much compensation will I have to pay? I received an experience certificate from them signed by the principal but not by the management. My monthly salary is 33,000, and I am from Karnataka.
