Dear Anuradha,
I endorse the views expressed by Mr. Raj Kumar. Legalities: The ID Act provides legal remedies only for non-managerial employees, so these senior-level employees are out of the purview of the ID Act. However, for managerial employees, legal remedies are available in civil laws. Such types of removal/termination can also be challenged in civil courts if all benefits due to them are not settled. Reinstatement is not possible. Instead of reinstatement, they can claim damages and compensation.
Regards,
Kamal
