I work at Foodtown, one of the big supermarkets in Auckland and love/hate my job.
The only reason I applied for the job in the first place was because my mate worked there, and offered me the job. I earn around $80 a week now, and work in the grocery department unloading trucks, and stacking shelves (quite physical), and 'facing up', which means bringing all the products to the front of the shelves, which is very tedious and time consuming. I really dislike the work, but my boss is friendly, and heaps of my school mates also work there, which makes it not such a daunting environment.
If I were you, get a job at checkouts- it's way easier than every other department. I am trying to change to their department in the summer.
By the way, pay is real crap considering how much work you do at supermarkets. Fast food outlets, and smaller shops pay more. Usually, the younger you are, the less you get paid. At Foodtown, your pay increases every year older you get. When I started, I was 16 and only on $8.35 and hour (before tax!), Then I got a random payrise to $8.49, then when I turned 17, got a even greater payrise to $8.90
Tax is real stink though, it cuts your weekly pay down a lot, but at the end of the financial year (whenever that is), if you are under 18, you can claim your tax back for some reason. My mate who works at a Butchers got $600 back from his tax- so its pretty sweet.
I don't really like supermarkets
Its better than manual labour, or being a rubbish collector
I'd probably have to talk to all the people's mums that I know, don't like that.
Yeah you have to be real polite to everyone you meet, and show them where stuff is. This has an upside though- at my supermarket, they have a thing called 'shoppers anonymous' where, each month, a secret shopper will come and asses you. You won't know who they are, but if you do everything right, you get a paid day off.
If I saw kids that I knew it'd be embarrasing, and they may make it hard for me to work
Loads of my mates work at my supermarket, and my other mates sometimes just come in to chat. Its not really embarrassing. Most people I know just come up and say hi. It's normally them who are embraced having to ask for help lol
The pay isn't probably very good
That is definitely a downside. Get a job at Nelson airport perhaps- it would be more fun

Mind you, in the last three months, I have earned enough to buy a car. I would have had a lot more if I didn't waste so much once I suddenly started getting money in my account. Try and save it if you can, it makes it all worth while when you seeing the amount start to add up on your bank statement!
