Pregnant employee

I was sick for a couple of days, i informed that i will be absent. When i came back, i presented my medcert and sabi nila cnendan na daw nila ko ng return to work order. They also gave me a notice to explain, which i filled up. When it was my time to talk to HR, nalaman q n pinalitan nung trainer ung 1st page ng document n pinirmahan ko at inattach yung 2nd page na may pirma ko. Ano po ba pwede ko isampang kaso dun s trainer o s kumpanya?

Im a 7th month pregnant woman. I was sick for a couple of days, i informed that i will be absent. When i came back, i presented my medical certificate and my sup said i was already sent a return to work order which i did not receive. They gave me a notice to explainw, which i filled up. When it was my time to talk to HR, I found out that the 1st page document that I signed was different from the one presented to me, what made me mad was that they attached the 2nd page that had my signature on it. I have proof that it is different from what I signed. What charges can I file and where should I file it? Will it be under DOLE?

did you inform them that the 1st page was changed? what was changed in the first page? you should inform the HR in writing.

Yes, i informed them. But they sided with the trainer. They said that they will give me a new one but I still feel that they did something illegal by doing that. What do you think?

Atty, humihingi ako ng copy nung sinubmit na inibang page. Dapat ko ba ilagay na for legal purposes?
