In indian raways Rly Board is the highest rule making authority. Earlier, reservation clerks in the computerised reservation office were working for six hours in a six days week. But recently the GM, E.Co.Rly's verbal instruction the same has been changed to eight hours with the number of working days. I want to know :- can a GM can change the working hours without the approval of the Rly Board, without proper job analysis and without consulting the recognised trade unions?
