how to file a complaint for bullying and unfair treatment

Hi, almost 3 years at work (non voice) and decided to resign due to career growth and told my supervisor 2 months advance. And now, I am currently rendering. That's when my supervisor started treating me so bad and my coworkers are bullying me.

Ever since I started my rendering days, it was hell for me and super unmotivated na ko pumasok. I am praying so hard na sana last day ko na.

I was once very close with my coworkers and always treated them with respect lalo na parang mga ate ko sila. I don't know how things turn out this way. This month lang, before I submitted my resig letter, they included me on a gc at work. I thought it's just a way lang so we can communicate kahit inside prod. When I backread, it was full of rants and talkshitting sa mga kawork namin on a daily basis. I know how they disturbingly talk shit about someone they randomly hate. Kahit wala ka naman ginagawa icchismis ka just cuz may narinig sila about you. It was draining sa araw-araw na nakakasama ko sila. I might not be their topic pero it still affecting me how twisted they do it all the time. I didn't last long sa gc nila cuz my sup remove me.

It started two weeks ago when I had a bad diarrhea and skip work. My supervisor messaged me to do an immediate o indorse nya na lang daw ako just cuz I skip work and kahit mag submit raw ako ng medcert she will still give me an IR dahil sa hindi ako nagpaalam on time. hindi raw porket rendering na ko, desisyon na ko and lots of very unprofessional things through pm and sa gc. When I got back to work, my coworkers gone cold and never interacted with me again. Turns out, nung wala pala ako last time kung ano-ano na pinagsasabi nila sakin. And now, even sa personal they will verbally parinig "tigas ng mukha", "kupal" and such. Right now, I'm only interacting with my two friend sa team. yung isa dun, sabay kami nag submit ng resig and yung other one, matagal ko ng kasama sa work at sya rin nagsabi sakin how they talkshit about me when I was gone. Sobrang eager nila ipaendorse ako.

My supervisor na pinapahiya ako sa work tuwing nalilate ako. This week nilapagan nya ako final warning cuz of behavior raw na madalas ako malate. With basbas from the OM cuz they are close as heck and they have favoritism.

Anyway, this is the third time na pinahiya ako ng supervisor ko kahit hindi naka one on one coaching simula nung nag render ako. Saying, "inendorse na lang kaya kita?" "dapat endorse ka na". Kahit yung ibang team inis sakanya dahil kung paano sya mamahiya ng agent.

I have been in this work place even before our LOB got created. My attendance never lower to 90 for two years. I have multiple lates din pero bihira lang ako umabsent. twice o thrice sa isang taon. Walang KPI work ko pero maraming pinahandle sa akin na trabaho.

This is my first ever work and I am currently graduating kaya I decided to resign. I want to have a clean record pero kung ganto rin naman, I want to file a complaint cause of the severe distress I am experiencing right now. I feel so so unmotivated to the point that I will book a ride even tho my work place is just 15 minutes away dahil tinatamad na ko bumangon. Everyday, before pumasok iniisip ko kung anong insulto ang marereceive ko sa shift or kapag may magawa akong mali sa work. Pati na rin kung sino ang magiging kashift ko sa team.

Please help a girl out.
