A 60-year-old electrician in Perth, Western Australia had been abusing his position and technical knowledge to squeeze in some recreation during working hours. Tom Colella used mylar snack bags to block GPS tracking via his employer-assigned personal digital assistant to go out to play a round of golf — more than 140 times — while he reported he was offsite performing repairs.



The tribunal found that the packet was deliberately used to operate as an elaborate “Faraday cage” – an enclosure which can block electromagnetic fields – and prevented his employer knowing his location. The cage set-up was named after English scientist Michael Faraday, who in 1836 observed that a continuous covering of conductive material could be used to block electromagnetic fields.
