Tray operators are workers responsible for managing and operating machinery that sorts, fills, or processes trays, often in manufacturing, food processing, or packaging environments. Their duties may include loading and unloading trays, monitoring equipment for proper functioning, and ensuring that products are correctly placed or packaged. Tray operators also perform quality checks, handle minor equipment adjustments, and follow safety and sanitation protocols. This role requires attention to detail, the ability to follow instructions, and sometimes basic mechanical skills.
