Dear Roopesh,

This is really an intresting topic as you have mentioned and a learning one also. By the way the best you can do is to decide along with your management and counsel him after that make him to give his resignation which will be safer for your company.

It is a difficult case but not an impossible one to be handled. Anyways all the best for you and your company and do share the outcome of this once it is solved for you, which will be certainly very useful for all our members in the forum.
