My previous job won't stop f-cking me. Please help.

A person I knew quit a months ago and a few days after that she was called back because apparently she made a mistake and was asked to pay a large amount of money. I feel like my friend is being f-cked. Now, months passed by, my friend apparently had signed a document as instructed by my friend's training officer while working on that very same job. My friend is now being asked to pay another large amount of money. Then a few days before their meeting for that issue, they called again asked her to pay another large amount of money for legal counsel.

Hindi ko maintindihan how this stuff works. Bakit sila yung nag-hire ng legal counsel for my friend? Noong nasa trabaho siya, siya ay trainee at lahat ng ginagawa niya ay utos lang din sa kanya. Hindi nya na tinapos ang training kasi sobrang toxic, t-ngina. Tapos noong nagquit siya, biglang may nakitang mali sa work niya at kakasuhan daw pag di nagbayad? Ngayon, may bago na naman? Ilang buwan na siyang hindi nagtratrabaho doon. Nakita daw on audit. P-t-nginang yan.
