Faye's Mate from the Gateway. They can't "want" you to sign it.
Either:
1. You are an existing employee and signing the AWA is at your sole discretion; or
2. You are a new employee in which case you have no option, either sign or no job.
If an existing employee, your employer should tell you the option to an AWA, which will probably be the Award. It should be a simple task for you to assess which industrial framework best suits you.
Regardless of all the ill informed commentary, AWAs are generally more rewarding and beneficial to the employee, than the outdated traditional Award structure.
