A Library Custodian is primarily responsible for ensuring that all areas of the library, including reading rooms, offices, restrooms, and staff spaces, are clean, organized, and safe for both visitors and employees. Daily tasks often include sweeping, mopping, vacuuming, trash removal, restroom sanitation, and refilling supplies, as well as routine maintenance like replacing light bulbs or performing small repairs. Custodians also help set up rooms for events or meetings and may work closely with library staff to address urgent cleaning or maintenance needs. This role involves a mix of independent work and collaboration, with some flexibility in schedule depending on library hours and special events. Working as a library custodian offers a vital behind-the-scenes contribution to the efficient and pleasant operation of the facility.
