Supervisors provide excellent coordination to teams of employees that move masses of soil, sand, equipment, and merchandise. Workers who pack moving boxes and transport freight and stock by hand, as well as workers who operate trucks and tractors, cranes, forklifts, and other vehicles, are directly supervised by material moving supervisors. These supervisors receive work orders and instructions from clients and managers, then divide projects into tasks and allocate them to teams of workers. Supervisors are in charge of staff hiring and training, as well as keeping their employees safe and productive. Work sites can be dangerous, thus it is critical to supervise the proper usage of safety procedures and equipment. Supervising project personnel necessitates record-keeping, the capacity to track both the minute details and the big picture, and interpersonal skills. The majority of these managers work 40 hours or more per week. Typically, a high school graduation or equivalent is necessary, as well as prior experience.
