Transfer of job after transfer of ownership

Dear sir, in the year june2014, elder pharma has sold its major two division to torrent pharma along with the transfer of employee and their liablities,but torrent pharma unfairly floated a conditional offer letter with changed services condition and given only ten days time to sign and revert back, without knowing our sides and clarification they closed the offer letter and seized our hard earned legitimate dues , and in between elder pharma also closed its operations, and from july-14 onwards i have been deprived from my salary and torrent pharma also took badli field workers in our place. few points to be noted here as why such situation came down---- [a] in elder pharma we have recognised grievance commitee and w wer given form a appointment letter under spe act. [b] torrent pharma didnot took more than 100 field worker who were on the leadership position of our trade union [c] in such circumstances where horrible situation been made by them i got fear of loosing my job if sign on the offer letter, hence i could not sign and ultimately loose my job and due wages also . [d] i filled my case before labour suptdt. and failure report has been sent for reference, in such conditions how to go ahead and what are the probabilities lying on,kindly guide me and sow the way i shall be thankful to you from core of my heart...
