• Harassment by private institute registered/affiliated under GTU/AICTE at the time of resignation

I had taken NOC from college 'A' where i was working at the time of applying in college 'B'. After successfully clearing the interview process at college 'B', I applied for resignation in college 'A' on 16 May 2018 wherein I requested them to relieve me from my duties on 30th June 2018. Principal received the resignation letter and gave me a received signature. After that they have not given me any written communication regarding the confirmation of acceptance of my resignation, confirmation of relieving date and amount to be paid by me against the notice period (if any). The 3 % yearly increment in the salary was received in the month of Apr and May 2018. But, the arrears of increment from July 2017 to March 2018 is unlawfully withhold without giving any kind of legitimate reason in writing for the period that I have already served the college. When I went to the principal with a letter to report the withhold of the arrears of increment, he refused to accept the letter and denied to give received signature on the application. I have sent them two reminders on 20th June (by email and hard copy through registered post) and 26th June (by email) but I haven’t received any written communication from them. The Principal had issued letter on 8th May 2018, wherein he has authorized the increased in my AGP from 6000 to 7000 after careful consideration by Performance Evaluation Committee for those who have completed Ph.D. However, this increase in AGP from 6000 to 7000 with effect from 01 may 2018 was not reflected in my salary of May. Moreover, I was issued this letter on 27 June 2018 (i.e. the letter was kept suppressed for 50 days). In my appointment letter at the time of joining college 'A', there is no mention of the clause of 90 days notice period. However, they are verbally asking me to deposit 69,202 Rs against the notice period of 33 day. I told them to give the same in writing and explaining calculation but they are not ready to give me anything writing and they have threatened to stop my salary of June and Gratuity. They say it is in the college rulebook. When I asked for the copy of the rulebook, Principal Sir said that he does not have the rulebook but Admin officer has. When I asked a copy of rule book from Admin officer, he did not allowed me to take photo copy of rule book either, instead he gave me rule book printed in 2007 for only for 5 minutes to read there only. The reason is that they themselves are running the institute without any rules and regulations and according to their own whims. On 30th June (i.e. my last working day in college 'A') they did not gave me relieving letter or experience certificate nor any valid reason in writing. Hence, I send them an email requesting them to stop harassing me unnecessarily. But instead, they have withhold my salary of June 2018. Gratuity is also pending. How can i get my salary, difference and gratuity?
