We have this probationary employee, and will end her contract 10 days before her probationary period. A month before her probationary contract ended , I already talked to the management for her evaluation if she would still be employed as regular or be terminated. Unfortunately, my boss had decided to terminate her 5 days before her termination she will be notified because of her low performance and rule violations. The management got so many transactions that she cannot mind the status of my co employee. As we decided to gave her the termination letter, she talked to my boss immediately and asked a month of extension.We gave her the letter 5 days before the she ended her probationary period in the letter it stated that she would have at least at the end of the month to turn over the files and responsibilities to the newly hired applicant. Our trainee complaints that she cant stand the attitude of our co employee, maybe she dont want that somebody gonna replace her. the management went on a out of town trip and she got the chance to be so rude to everyone. Because of the grievance she made, i tried to talked to her but because she is older than me, she dont want to listen. I texted my boss regarding that issues, and she called her and they argued in the phone. 4 days after her probationary period ended she decided not to go back in the office without any turn over, she doesnt answer the calls and texts. The worst part is, we found out that she got so many anomalies taken in the fund. What actions should be made and should be considered if we are going to file a case for her?
