Officers within the Warren Police Department now are working 12-hour shifts.
Deputy Police Chief Louis Galoso says many officers within the department are working the longer shifts after the officers' union agreed to the shifts change.
Galoso says the department now has several overlapping 12-hour shifts, as opposed to the traditional 8-hour shifts. He said Warren police are working on a "trial and error" basis.
The department will try this out for a year and will go back to the old shifts if there is a problem.
In contrast, Detroit police recently switched back to 8-hour shifts after being on 12-hour shifts which were implemented under the former police chief. Chief James Craig, who took over this year, said morale was the main reason the Detroit Police Department went back to the shorter shifts.
