PUBLIC SERVICE WORKER III

DEFINITION OF CLASS:
This is semi skilled manual labor work in the maintenance and repair of County roads and property, including operation of 10,000 - 15,000 GVW trucks (and over 26,000 GVW trucks in the Division of Traffic Engineering and Operations), tractor mowers and similar vehicles, some with power take-off equipment. Contacts are generally limited to the members of a crew to which an employee is assigned and involves receiving and providing information. This class of work may entail some public service/assistance, but it is incidental to the primary focus of the work performed.
An employee in this class independently performs a variety of tasks based on prior experience or training and prioritization by higher authority. Work may involve leading/instructing unskilled employees in the performance of their work. For most duties, the supervisor does not give detailed instructions or provide continual supervision; the employee is expected to complete assignments after receiving initial oral or written instructions. The nature of the duties and the kinds of equipment used require instructions/practice on the equipment and continual care and attention by the employee both to avoid accidents and finish the work properly. Also, the employee is responsible for completing assignments involving several tasks or processes that require remembering directions, sequences, etc.
The employee typically works as part of a crew, and is expected to carry out previously performed duties with very little or no instruction from lead/supervisory workers. Work is generally performed outdoors in tiring and uncomfortable positions for long periods, e.g., employees continually bend, reach, stretch, lift, stoop, climb and crouch, at times in cramped quarters and/or awkward positions. The employee regularly exerts medium physical effort, such as pulling, pushing, lifting and carrying items weighing up to 50 pounds, and occasionally performs heavy physical effort, such as pulling, pushing, lifting and carrying items weighing over 75 pounds. The employee, by working close to heavy traffic, operating power tools/equipment and being around moving machinery, is exposed to hazards that require constant awareness, adherence to special safety shoes, hard hats, ear protectors and/or respiratory masks. Work is performed outdoors where the employee is regularly exposed to severe weather, grease, dirt and muck from digging and working amid run-off, storm drains and catch basins, asphalt and other bituminous products, noxious or malodorous fumes, high levels of dust and similar unpleasantness and discomforts.
