They didn't gave any such costly training, i only undergone by the inhouse training.They are asking to sign now in DOJ. How it could be? how can i sign in legal paper in back date?They should took sign at the time of joining.I have to pay Rs. 50,000/- if i left company before the bond period,but if i cross the bond period there is no such advantage.If i sign then i will be bound for 2 years,in the time of increment maybe they will give me a average or no increment,in that situation i will not leave the company also because i am bound for 2 years.
Now, if you feel that by signing the bond you will become a slave and you may not get any increments etc, then don't accept it, refuse the demand and leave the organisation. A company which can ask employees to sign a bond on backdated can even ask them to leave the company for no reasons. If the case is about a probationer, the law also permits such termination.
It is not at all a good practice to sign any document backdated. But I would like to have an idea as why you were agreed to sign the bond at the time of your interview. The fear of no increment / low increment could be in your mind at that time.
