I am processing it all and doing research for myself and sharing my feelings of frustration.
Modern award for cabin crew here :
http://www.airc.gov.au/awardmod/awards/cabin_crew.pdf
Search for the no disadvantage test refers to the new "better off overall test" which compares agreements to the modern award.
A yes vote we will get what we have on the table. A no vote and we could at worst be on the modern award.
Part of my processing is working out what will be better for me. The eba on the table is better in most areas than the modern award. Especially the 156 hours in a calendar month before overtime. The displacement at any time. The 90 min sign on. Etc.
Do your own research people. Fair Work Australia has a great website.
