Managing staff is tricky, yes... but that's no excuse for systematically and deliberately underpaying them as part of the company's business model. This is about restaurant owners deliberately underpaying their staff, in order to pocket greater profits themselves. It's not about managing staff shifts.
I haven’t read any of the ins and outs. I do know that if the Alice Springs golf club was audited, there’d be a substantial underpayment but not to do with anything other than not paying OT when employees didn’t have their unpaid breaks.
