Hi Team, I joined FYERS as VP - CS and sales on 16th jan'24 however they ended my employment suddenly on 5thApr'24 in retaliation since I reported continued hostile, intimidating and unprofessional behaviour by SR. Manager sales on 3rd Apr '24 in writing to VP -HR of FYERS. As a result FYERS moved one of my KYC process to another VP on 4th Apr and ended my employment on 5th Apr'24. They withdraw my access to all systems, emails and chat on 5th apr'24 itself and FYERS -HR send me a email that I have resigned and is not equired to be available in office for next 15 days of notice period when I haven't resigned till today from FYERS. When I questioned them and asked them to share my resignation. They created new story saying that I there was difference in expectation between them and myself about role. When I challenged that saying CEO himself was appreciating me and all. They said, I resigned since my performance was an issue during probation period of 3 months when they never issued any mail Or notice to me on my performance till today. They haven't paid me my notice period pay of 20 days for Apr'24 nor have paid me any severance pay which I requested nor have issued me any relieving letter. In fact they send me full and final payslip yesterday for Apr 24 showcasing LOP days -20 . What can I do in this case, pls guide.

Actually my wife is working with company since last 3.0 year and now company has immediately sue her and revoke her access to email and teams without intimating actually she has also joined office after 28 days by giving the birth of baby and she had supported the company in maternity time and joined the office early due to more pressure from employer good thing is she is having a very good performance in company still he fired from company
