In a worker management system comprising a terminal device, a worker detection system, and a site management device, the terminal device transmits a worker signal, which includes terminal GNSS positional information represented by a GNSS coordinate system of the terminal device, to the site management device. The worker detection system transmits worker detected positional information, which indicates a position of the worker detected by a surrounding monitoring sensor mounted on the work machine, to the site management device. The site management device relates the terminal GNSS positional information to the worker detected positional information, and when both information for the same worker is available, it selects a position indicated by the worker detected positional information, and when only the terminal GNSS positional information is available, it selects a position indicated by the terminal GNSS positional information, as a current position of the worker.
