Tom Colella , an electrician from Perth , Australia , took skive off work to new level . On at least 140 freestanding   occasion , he conceal his troupe - mandate , GPS - enabled personal digital help ( PDA ) in an old packet   of Twisties to keep his employer in the dark as to his real location .

And what ’s more , his employers appeared to know he kept his PDA safe in a chipping mail boat and they take to allow it . Colella ’s wily   actions were only investigated after an anonymous tip - off lay claim he had been out golfing when he should have been at oeuvre .

When Colella was let go from the company , he lay claim unfair   dismissal and the incident was put to the Fair Work Commission .

Bernie Riordan , the   commissioner involved in the case , wrotein his determination :   " I note that Mr Colella ’s supervisors knew that he lay his PDA in the foil bag and that they should have lie with the effect that this action would have on the PDA twist …   I can not sympathize why Aroona condone this praxis but it clearly shows that Mr Colella did not require to be dog . "

Colella was able to turn his put away chipping packets into a fairly effective   – if greasy – makeshiftFaraday cagebecause the aluminum and mylar credit card in the foil make it electrically conductive . This turns it into an electromagnetic carapace that   can block the comparatively debile GPS signals coming from the   twist , thus keeping Colella ’s emplacement a mystery .

While Colella may have used his professional smarts to elude detection via GPS tracker , he let a routine of thing slip , which , finally , essay to be his undoing . For model , suspicions were raise when his name did n’t turn up in his clients ' access and gate logs .

According to thecase report , " Mr Colella regularly works at the Neerabup Water Treatment Plant ( NWTP ) . The NWTP is a fenced facility with an electronic gate . The logic gate logs at NWTP did not discover Mr Colella entering or leaving that facility on any of the describe days . "

And every now and then he would take his PDA out of the chip bag , leaving GPS data confirm he was at home when he should have been do work . Perhaps most damning , there were also instances when he did n’t get the job done .

" Aroona take that the Chlorine Analyser Records at NWTP show that Mr Colella did not perform the necessary tests and calibrations on the Cl analysers . Aroona arrogate that Mr Colella ’s actions resulted in a significant health peril for the residents of Perth . "

Unsurprisingly , the commission prefer to preserve the ending .

According   toNPR , Colella is now working as an Uber number one wood .
