What case can I file against my supervisor?

Hi. I would like to seek help if it is possible to file a complaint or case against my supervisor. My supervisor filed a case against me under falsification of documents but this wasn't proven because of lack of proof. My supervisor did not talk to me first and instead, he immediately escalated the complaint to HR. What my supervisor did was really bad and it destroyed my reputation in the office. What possible case (or HR case) can I file against this supervisor? Thanks!

These are my suggestions:

1. Check your company handbook and look for the appropriate offense regarding profane/vicious or obscene remarks or gestures intended to offend any person/employees adressed during working hours or within the company or similar offense like this. You can charge him with this kind of offense as long as you have evidences/witnesses to support that your supervisor did this to you.

2. document all your actions, emails/letters, this is your defense in case the company will not make an action since you are complaining to a leader you can raise this concern to DOLE or NLRC but i do suggest to settle it first in your HR.

you can file a complaint with HR

Maghanap ka ng taga HR at hanapin mo saan papasok ang policy ng proper filing ng case.
Kung sumunod ba si supervisor sa flow. Kapag hinde null and void ang kaso nya sayo.

Mag counter charge ka ng abuse of discretion. Tignan ko tanggal yang bisor mo.
