Employee groups can be set up when there are employees that are categorized the same way and take the same training. This makes it easier to assign training to a group of people rather than assign them one at a time.
For example, there might be a group of supervisors that need a specific sexual harassment prevention training course and another group of employees who need a different sexual harassment prevention training. By creating employee groups, these supervisors or employees can be grouped together. This makes assigning trainings easy.
