Abstract: A workplace management system includes a wearable device and a cloud server. The wearable device includes a processing chip and a communication chip connected to the processing chip. The cloud server is in communication with the wearable device. The cloud server includes an operating module, a transceiver module, a storage module storing working mode data, and a processing module. The processing module is configured to apply a current working mode data from the working mode data stored in the storage module according to an instruction given by a user using the operation module, control the transceiver module to transmit the present working mode data in an electromagnetic form, control the transceiver module to receive a response message generated by the wearable device in response to the current working mode data, and control the transceiver module to transmit a call message according to the response message.
