Pep Trading hours

Not happy with Management of Pep 6290 Mooiriver mall on how the staff is shouted at. And their working hours,the shop closes at 18h00 why are they leaving at 19h30..19h45 ??With mostly females working there,their safety should be b a priority and Get PAID OVER TIME or strictly stick to their working hours if PEP doesn't pay for overtime
