John Halpin, a 21 year employee of the NYC school system was fired yesterday for accepting pay for time worked when he allegedly was not at work. How do they know he wasn't at work? It appears that they were monitoring his activities using the GPS functions of his government-issued cell phone. The NY Post reports, "Schools Chancellor Joel Klein yesterday fired a veteran worker whose movements were tracked for five months through the GPS device in his cellphone, leading to charges that he was repeatedly cutting out early." He said he was never told that the cellphone he was given in 2005 could be used to monitor his every move and questioned the accuracy of the data it produced. The judge issued a decision saying the Department of Education was under no obligation "to notify its employees of all the methods it may possibly use to uncover their misconduct." Only 2 states in the U.S. require a company to let an employee know when they are using a GPS tracking device. We know of companies who monitor Internet and phone usage, now they are tracking movement. Eyes in the sky.
