There is difference between dismissal, removal and termination in terms of the separation of the Employee. Your word is vague and is not clear on this aspect.
More over, as per the attachment which is the definition of the worker as defined in the ID Act, 1947 as amended upto date, i think ID Act will not be applicable on the Manager.
More over in addition to the misdemeanure of the Manager you have to follow the certain guidelines of the domestic enquiry for the dismissal and removal from service of the defaulting Manager in consonance with the guidelines of the standing orders as well as terms and conditions as agreed at the time of the appointment.
As far as termination is concerned is meant for the probationar employee everywhere and the cause of termination is defined usually in the letter of appointment itself if certait terms and conditions are not met. For termination domestic enquiry is not required but requir to serve a Memorandum for the termination so that you may give Manager the opportuinity to explain his sort of the reply for the misdemeanure if any. After considering his reply only you may decide what action is needed and what not.
thanks to all.
