I was provided with 2 days fake sick leave whom I used to give to the HR last June. They have known that it was fake, I apologize verbally and was ready to face the consequences of a warning letter and salary deduction. None was provided by the company at that time. After 3 months, as soon as I came back from vacation, they have handed me my immediate termination stating about the forged documents which shocked me. The company has used their time to find a replacement for me and as soon as they got the person, they terminated me. I was working in that company for 3.2 years and I never had any warning memo. Any of you guys know what to do?
