QT - I was in the job for 31 years and enjoyed every moment of it. Most posters here will only post the negatives because it is a place to vent.
Sure ASA are not the world's best employer but they are not the worst either. Just look at the UAE threads, FAA, UK NATS and you will find the same complaints and gripes from those employees too.
The only way to know is to have a go. At least with ASA you'll get paid to train, most other organisations make you pay to get an endorsement. Here at DFS the trainee salary is much less than that on offer in Australia so dont be convinced by what you read here, make up your own mind.
I am returning cause I now know that as an employer ASA is just like many of the other ANSPs worldwide, but Australia is so much better a place to live!
