JB Hi Fi boss Richard Murray urges facemask wearing if required but calls out abuse against staff during pandemic

JB Hi Fi's profit has surged on demand for home electronics for the stay at home office - anything from computer monitors to coffee machines to robotic vacuum cleaners. 

Chief executive Richard Murray backs mandatory facemasks for staff and customers if that's the medical advice - but he's more concerned about bad customer behaviour towards his workers. 

Mr Murray tells ABC's Peter Ryan the legislated rise in employer superannuation to 12 percent might need to be delayed rather than abandoned.
