In regards to REST, join unless you already have another superannuation fund.  At this stage I don't think it matters, in the two and a bit years I've been at woolworths I've only ever had two occassions where I've qualified to receive a company contribution (being under 18 and all).  Just fill out the form.  What you should give good though to is whether or not you will join the SDA union.  I did, and while I think I'm better off for it (pay disputes with woolworths and all), others think its a big waste of money.
 
 
Anyway, my region needs a new HR Assistant, Saturdays, 7.30-4.30, to run inductions.  I'm seriously considering applying.  Has anyone else applied for this role/acted in this role? Any thoughts on specifically what it would involve.  I will ring my HR officer on Monday, but in the meantime, thought I would ask here.
