Poor management s****s

I was shopping at pick n pay boardwalk Richard's bay and noticed the manager Rita shout and yell at a cashier. When the cashier wanted to explain what had happened. She said that she was not interested in listening to her. All this in front of customers is this how managers handle queries, by belittling their subordinates in front of customers. The said manager has no ethics morals empathy nor respect in handling issues. She needs to be trained in employee relations and hr management s****s. She should have called the cashier into the office and addressed the issue. To top it all a customer who was waiting to cash his purchases threw the items onto the conveyor and began shout at the cashier. Is this how managers at pick n pay treat their front end staff. The very people who have to smile and greet customers. These are the people who should be respected and treaded with dignity as they make the store.
