I don't think you're a shelf filler at Kwiksave these days right? Not that there's anything wrong with it if you are.
It would physically kill me now, that backbreaking work is for the young. I left in 1985 and a year later entered IT. The missus works in a supermarket now. Despite it being almost 40 years later, the conditions still suck and staff are treated like shit.
Some things.., don't change.
I think it's the same here chops, supermarkets I mean. Not nice work although we have all those shoppers who go around shopping for online purchasers and home delivery...probably not too bad a role. (But staff are treated as you say.)
