Thirty two on-duty Pittsburgh police officers were forced to work traffic control for a recent Beyoncé concert due to an insufficient number of volunteer sign ups, the police union reported.
Thirteen of the officers were taken out of their normal work areas and nineteen were asked to either stay late or come in earlier than their normal shift hours.
The union has said that forcing their officers to work the concert violated their contract.
"This is strictly an issue of secondary employment and the officers’ right to choose what type of secondary employment they engage in,” said FOP president Bob Swartzwalder.
The union had previously said that any attempt to force officers to work the concert would prompt the filing of a work grievance.
