A bailiff is a law enforcement officer or guard at a courthouse who ensures the security of the building and the safety of personnel and visitors. As a bailiff, you may work inside the courtroom to maintain order by managing disturbances, escorting out unruly individuals, and guarding sequestered juries. You are also responsible for ushering judges, jurors, witnesses, and spectators into the courtroom. If you work as a bailiff at the entry of a courthouse, your duties include using a variety of security equipment, including handheld wands and X-ray machines, to screen individuals entering the building.
