All govt jobs are offered under 1 yr or 2 yr contract nowadays, if you don't do anything majorly wrong you can expect to be converted to permanent staff after the 1 or 2 years. Govt still a stickler for rules and regulation so just do your job well, be punctual, do OT if you must finish work by deadline, don't complain, don't gossip, don't take more than 5days MC in a year, be very very obedient and you will definitely get there. =)
