Worker fired for disabling GPS app that tracked her 24 hours a day

In short: an employee was fired for disabling a GPS tracking app that was installed on her employer-provided work phone. Said app ran 24 hours per day, whether she was on work hours or not.

The employer required the employee to leave the phone on 24/7. Fine. But if it was in a Faraday cage, it would still be on, but it wouldn’t be able to receive or transmit radio signals.  Alternatively, employ a GPS jammer. It seems that these might also block cell phone signals (up to 10 meters away), but hey, the phone is still strictly speaking *on.* I gotta wonder about the legality of a cell phone jammer that reaches out far enough to wipe out conversations in other cars while you’re commuting to work, though…
