Here’s an off-the-beaten path piece from Naked Security about the efficacy of almost anything an employer might issue to track his or her employees during business hours. The employer of an electrician in Australia issued a GPS-enabled personal digital assistant (PDA) to an employee who, sad to say, placed it in an electrically conductive “cheese curly crunchy snacks” bag and went off to play golf instead of working.
The bag was electrically conductive and made an excellent “Faraday cage” for mobile devices. (A Faraday cage, explains Wikipedia, “is an enclosure used to block electromagnetic fields. … Faraday cages are named after the English scientist Michael Faraday, who invented them in 1836.”) “It’s a pretty greasy way to block electromagnetic current and to thereby keep your employer from tracking your whereabouts.”
But, finally, the employee’s wayward ways were detected and he was fired. “It was determined that he had been going AWOL to play golf – more than 140 times – while reporting that he was working.” Familiarity with the nuances of modern life is essential for truants of any ilk.
