You will have to refer to your company policy.

Legally, they can file a case against the employee and ask for recovery of money spent plus compensation.

Agree with expert . additionally.. they can ask you to pay ONLY if they trained you and expenses were incurred by your company in imparting technical training to you if it is a 'Training Agreement"

Thank you Mrs.Jayashree and Mr. Praven Kumar for your replies.

Actually, Employee's knowledge towards a proprietary tool is used for development of project at onsite (US). There was no training given to develop the skills of the person. The company wants the people to work back in offshore (india) upon return and it is faked under "training agreement" which is actually a bond.

A similar query is being discussed at another thread:

The training that is provided to employee to manage the counters/work of employer should be without any cost to employee.

The employees in IT/ITeS sector are themselves responsible for their plight as they felt that unions and unity is not for them and becoming member shall lower their status.

The employees that are not united are like sitting ducks and are susceptible to exploitation.

The united employees in your sector have done many goods jobs.
