First-line supervisors get to teach and work closely with others in performing their regular job duties. These supervisors generally coordinate employees from the ground, ensuring a smooth operation during working hours. In non-retail contexts, this can mean managing inspectors, machinists, toolmakers, and others involved in manufacturing processes.
