Mr.Anant Pradhan,
Re:Your stand and view point, there is a word of caution. In the option of enforcing, virtually, to resign en masse, might cause some unrest in employees, especially those put in considerable yrs.of service. Some may not be willing to resign, instead might insist on regularisation or like a migration/transfer of past service into new entity. Therefore, it would depend on the mind set of employees and resultant payouts if any like settlements towards EPF, Gratuity, bonus etc. So you have to necessarily take these into consideration before finalising your 'modus operandi' a frame work. Possibly, there could be division among your employees, no consensus. I would suggest an 'option' route to bifurcate between them and take a call depending the ground reality.
