What does a police sargent do?

A sergeant in the police department is basically a first-line supervisor of the rank and file officers. He/she conducts roll calls and briefings of officers at the beginning of shift or during special operations. He/she makes sure that officers are doing their jobs when responding to calls or dealing with the public. Sergeants handle most of the complaints that are made against the officers under their supervision. They handle the basic time and attendance, counselling, and scheduling paperwork.
