MACHINIST

3283N2

Pay Grade:  20

DEFINITION OF WORK

Summary

This is skilled machinist work using machine shop equipment in the design, construction, installation and repair of metal parts, tools and machines. The work of this class involves the operation of precision tools in the fabrication or in the replacement of components and parts. Also, work is performed in accordance with accepted trade practices.

Standard Classification Factors

Supervision Received - LEVEL B: "Under general supervision…" Employees working under general supervision usually receive some instructions with respect to the details of most assignments but are free to develop their own work sequences within established procedures, methods and policies. They are often physically removed from their supervisor and subject to only periodic checks.

Difficulty - LEVEL C: Considerable… Duties which require a high degree of concentration because of the many factors which must be considered and weighed before a decision can be reached. Usually positions that require planning, developing, and coordinating programs and directing fairly large groups of people fall into this category.

Complexity - LEVEL C: Work is of a standardized nature that may involve a variety of duties. Analytical thought becomes more important at this level due to increased data and changing situations. Tasks usually have several steps, some of which may not be directly related. Alternatives may exist for processes or methods to be used in solving problems. Workers at this level exercise a moderate amount of independent judgment. Work is controlled by routine review and reporting to or consultation with supervisors. When guidelines exist at this level, they tend to be more complicated or technical in nature requiring careful interpretation.

Consequence of Actions or Decisions - LEVEL D: Consequences of actions or decisions at this level are significant as the work may be rarely if ever reviewed, making errors difficult to detect. Errors may cause major program failure or a high degree of confusion. Injuries to others due to errors are serious or incapacitating or both and costs due to errors are substantial.

Contacts - LEVEL A: The purpose of the contact is to obtain, clarify, give or screen established factual information, regardless of the type (i.e., easily understood or technical) within a well-defined relationship. Normal communication skills are required.

Physical Demands - LEVEL C: The work requires moderate physical exertion.

Environmental Conditions - LEVEL C: The work environment involves hazards, risks or discomforts typical of working with or around machinery with exposed moving parts, irritant chemicals, heavy equipment or abusive or hostile clientele and patients. Exposure to disagreeable weather conditions and extreme levels of temperature, ventilation, lighting and sound are normal. Protective clothing or gear and specific safety standards or procedures may be required. Serious injury is possible.

Supervision/Leadership - LEVEL B: Involves functional leadership responsibility. As a "senior worker", performing essentially the same or similar work as those overseen, responsibility includes training, instructing, scheduling and reviewing. As a "project leader" may be responsible for a phase(s) of a single project which includes planning, coordinating and reviewing the work of others. This level may also involve limited administrative responsibility such as participating in the evaluation of work performance.
