The purpose of the present invention is to provide a technology for generating a
work shift in which requests from operators are easily reflected. This work management device is characterized by comprising: a storage unit for storing an operation
list including a plurality of operations having at least the start times and the end times specified, operator data including a plurality of operators who engage in any of the operations, and
work shift data in which the operation
list and at least one of the operators scheduled to engage in an operation are associated; a recommendation
processing unit for, with regard to an operation lacking an operator scheduled to engage therein, executing a process for extracting, as a candidate, an operator who is not scheduled to engage in any of the operations in the operation
list on the same day, and a recommendation notification process for inquiring the candidate whether or not to accept the engagement in the operation; and a vacancy assignment unit for executing a process for receiving an inquiry result, associating, as an operator scheduled to engage in the operation, the candidate who has accepted the engagement, and including the candidate in the
work shift data.
