Dear Sir

I am in a situation, I worked for a big IT Firm, went to onsite for some time. Left the company with in a year after coming back as was not getting good opportunities to grow with in the project and there was no chance to leave the project, even HR was helpless in this. After six months for F&F they asked me to pay my salary component. their argument was its a company policy that if an employee leaves the company with in a year and have stayed longer than 3 months then he has to pay this component back to company. this is around 50k not a small amount for me.I asked them how can they expect me to pay my salary which i got after working for them.and if their was such rule why it was not brought to my notice before i went onsite.Please suggest me am i supposed to pay this amount or is their anything i can do against such company.

Thanks in Advance
