Any authentic EBA/AWA has to be reviewed by the OEA. It can not, by law, be less than the Award.
Once written, it gets sent for review to make sure that no employee will be disadvantaged compared to the award.
If you need help or information on EBA's call 03 96994200.
Bill, read this thread. Thanks for repeating and reinforcing my earlier advice.
But, hello.............., no one is listening!
