First, TRY and get used to calling it Woolworths from now on, the Safeway name is being phased out (this will prove useful if your store gets a refit soon - not so useful if it isnt i suppose).
What do I do if I get accepted for "long life"? Presentation, capping and running stock (i.e. basically moving stock - a lot)
How long does the induction go for? When i did it it was 8hrs induction, 2 hrs fresh obsessions training, 3 hrs register training (NOTE: this was 4 years ago now)
Should I wear my school wear for it(if I get accepted) Smart-casual may be better, depending on how "neat" your school uniform is
How much will I get paid(15 years old, casual/part time) If it's the same rate as NSW ~$12 per hour as a casual
What do I need to do eg tax file number, make a bank card.. You WILL need a bank account and account details, and a TFN would be desirable/
Safeway supply the work wear right? Or do I need to purchase it off them? not sure, when they introduced the new uniform casuals got 1 free, and permenant part timers got 2. the shirts arent that expensive though ($15 when they first came out - not sure what they are now tho), you will need black pants and leather shoes.
Anything else I need to know? Start off doing as many shifts as possible, it will make it easier to get your way later on down the track - trust me
What's this new Safeway Card all about? Not sure what you mean - unless your referring to either the Woolworths Everyday Rewards Card [this stores fuel discount offers] or the Woolworths Everyday Money Credit Card [new credit card that earns rewards for shopping at woolies]
What's a TFN? a Tax File Number, you should get 1 regardless of whether you get this job or not, details at ato.gov.au
