The second is a CAR isued in Aug 2005 requiring Pilots to give 6 months notice before jumping ship.
6 months notice is an Ordinance issued by govt covering not only state run airlines but also other essential services under govt , STOPPING skilled/technically qualified working in various govt services to leave for greens.
when pilots starts leaving govt run airlines eg AI in 1995 or 2004 ,
DGCA implemented it.
i think GDCA staff also will have same problem of 6 months notice period
basically 6 mnths should be applicable to only state run companies not the private ones.
CARs are issued by DGCA from time to time based on Aviation situation and requirments.
