Janitors are professionals responsible for maintaining cleanliness and order in various facilities, such as schools, offices, and hospitals. Their duties typically include sweeping, mopping, dusting, and emptying trash bins. They may also perform minor repairs and ensure that restrooms are stocked with necessary supplies. In addition to cleaning, janitors often play a role in safety by keeping walkways clear and reporting any hazards. They may work alone or as part of a team, and their work hours can vary, often including evenings or weekends to minimize disruption in the workplace.
