Yep agree with you on this.
As an example in the old days of PMG then Telecom Australia there were more than 80,000 employees (now they have around 30k staff), because they had people in the exchanges literally reading the amount of minutes of calls each phone line had made every month for the bill, off counters on the exchange equipment.
Imagine how expensive calls would be today if unions forced Telecom to keep all the staff and stick to the old work practices rather then adapt to the new technology. This is what is happening to Qantas..
ie. Maintenance of modern aircraft A380!
Unions did this to Ansett. good example is 3 pilots in 767's. At that time it was thru only airline in the world to do that. everyone else changed to 2 pilots with upgraded coughpit.
We'll never learn.
