Verbal Suspension of employment - haven't received any formal notice regarding LWP or suspension notice

Dear Experts, I was working with a startup based out in Noida. Last month (May 2020) my manager called me and told me to go on 'Leave Without Pay' - Verbally. However, I haven't received any formal notice regarding LWP or suspension notice.
I want to know how can I claim my salary? What would be the right procedure? The company has put just three employees on LWP as a part of politics, and they are doing well in terms of Revenue Generation. By all this, I am going through a lot of trauma and depression, as I was at the peak of my career. I want to teach a lesson to such companies who ruins the career of aspiring employees.
Thanks

No Neha - don't resort to such violent actions and reactions. Politics in workplace is a hyped-concept. Don't succumb to it !
Practical advice: Please tender resignation notice to your employer clearly stating reasons. Here, the burden of action will now lie on them - not you. Let them decide for themselves. For sure, they will take it to written terms - as you always wanted. As a part of your appointment letter - you are free to resign at your own will anytime you want - serving a notice period and your salary will be processed as a part of FNF, legally. Be professional in your communications, please.
Plus, search for a job outside of your current Organization - aggressively. You will never be better off at this place, it seems. Better, change your job for good.
