Man fired after employers track his movements on GPS phone

John Halpin, a carpenter supervisor for the NYC school system, was fired for falsifying time records. His manager had been tracking Halpin's location on Halpin's GPS phone (provided by the school system) for five months, and noticed multiple discrepancies.
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.

But neither argument swayed administrative law Judge Tynia Richard, who found Halpin guilty of submitting false time records when he left early on numerous occasions between March and August 2006.

She 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."
