-current good conditions like sick leave and URTIs were contained in awards which unions put a case forward for and were awarded by the government
-under Workchoices all award conditions have been stripped back to the MINIMUM standard of 5 things-see Office of Employment Advocate
www.oea.gov.au
-the unions can only hang on to conditions when they are supported by the majority
-once you reject an agreement, all things negotiated are off the table, and the company may start again with the bare MINIMUM literally!
I've seen it happen to all the staff-ground staff & flight attendants-in another airline. Believe me, there's no negotiation because there's no law that says an employer has to bargain in good faith-see
www.actu.com.au search 'good faith'.
My advice is get good sound advice and stick together.
