don't forget that come july 1 and your agreement is not successfully voted up labor's new fair work oz will begin. a fairness test i.e. new agreement must not disadvantage any employee, will apply. further, union representation if requested cannot be refused. lastly, employers must negotiate in good faith, massive fines if they don't.
so if the no vote prevails little is lost (by the sounds of it) and maybe a lot to gain from bargaining after june 30.... something to think about.
p.s. i work for the white rat.
good luck to you all
