METHODS AND SYSTEMS FOR IDENTIFYING AND ADDRESSING WORKER FATIGUE
Methods and systems for identifying and addressing worker fatigue are provided. Work data associated with a worker of an organization is identified. The work data indicates at least a number of hours worked by the worker during one or more intervals of a time period. A fatigue state associated with the worker during the time period is calculated based on the identified work data.
