...Colella's managers were aware that he kept his PDA wrapped in a snack bag. In his decision, Riordan wrote, "Mr. Colella’s supervisors knew that he placed his PDA in the foil bag and... should have known the effect that this action would have on the PDA device." Riordan expressed confusion over why Aroona managers condoned the behavior...
So we know he wasn’t discrete. If you are going to use a covert method of disabling your tracking device by blocking the GPS signal using off-the-shelf mylar snack bags, the least you can do is to be discrete so that it isn’t obvious when you drop the tracker in the bag. Poor headwork if he really wanted to keep that job.

From what I’ve been reading, Uber will soon replace him with an autonomous vehicle so that job won’t last long either.
