Attendance-tracking system not successful in Columbus (Ohio) district

From The Columbus Dispatch: Only 15 percent of Columbus (Ohio) schools employees are using a $1.7 million computer system that district officials said would improve how they track all employees' attendance. The system was billed as a database that would track the hours worked down to the minute by the district's 7,300 employees. But district officials did not understand until too late that most of its employees could simply refuse to use the system, labeling it a change in work rules that needs to be collectively bargained into union contracts.
