MASON AND PLASTERER, GRADE 12
New York State Department of Civil Service
NATURE OF WORK
Mason and Plasterer performs journey level masonry and plastering work and frequently supervises others in the construction and repair of buildings and structures involving the use of a variety of masonry materials including brick, stone, plaster and concrete.
Mason and Plasterers are employed by many agencies with the greatest number of positions in the Offices of Mental Health and Mental Retardation and in the State University.
CLASSIFICATION CRITERIA AND DISTINGUISHING CHARACTERISTICS
Typically a Mason and Plasterer supervises a work crew normally consisting of less than ten Maintenance Assistants, Maintenance Helpers, Laborers, and occasionally other Mason and Plasterers including the planning and layout of work. Such supervision is generally exercised on a project basis and involves a maintenance crew of two to three semiskilled or elementary skilled positions for each journey level Mason and Plasterer. In an agency such as the Department of Correctional Services where inmates or residents perform some masonry tasks, a Mason and Plasterer may work with, lead, and provide practical instruction to a small group of such individuals.
A Supervising Mason and Plasterer supervises large scale masonry operations involving ten or more skilled, semiskilled, and relatively unskilled personnel. Such personnel may include those engaged in crafts other than masonry.
A General Mechanic may also perform journey level masonry and plastering activities. However, such positions are classified only where the incumbents perform skilled and semiskilled level work in a combination of trades.
In many State facilities a Vocational Instructor specialized in masonry formally instructs inmates and/or residents in the practice of the trade.
Maintenance Assistant (Mason and Plasterer) as a semiskilled employee, performs many of the manual tasks of the masonry trade but is generally not required to plan and lay out work. Incumbents may perform journey level activities and tasks under supervision or after receiving detailed instructions.
Maintenance Helper assigned to a masonry crew assists in construction and repair work performing the heavier, less difficult, and repetitive activities involving elementary skills while learning the trade.
Employees engaged in other building and maintenance trades are classified under a variety of commonly used titles descriptive of their work such as Carpenter or Electrician.

RELATIONSHIPS WITH OTHERS
The nature of a Mason and Plasterer's activities generally restricts relationships to employees working within the same organizational unit including artisans in other trades. On occasion, however, incumbents may be required to orally communicate with others in a State agency or facility on the reasons why work is being accomplished in the manner selected.
Typically, they supervise a masonry crew which may include State wards. Such relationships are characterized by frequent verbal communications in assigning work and providing instructions. Written and oral communications with the general public are not typical of this class. The tasks of this class are predominantly thing oriented and the involvement with others is not a factor in determining classification.
NATURE OF SUPERVISION
Mason and Plasterers are usually supervised by higher level trades positions such as Supervising Mason and Plasterer, Maintenance Supervisor 1, or Maintenance Supervisor 2. Generally work priorities and the nature and extent of the work to be performed are prescribed and materials are furnished. However, in the absence of such direction a mason may set priorities, requisition materials, and determine the work that has to be done. I
Although the work of a Mason and Plasterer is inspected periodically by the supervisor, incumbents are expected to work with considerable independence as is typical of a skilled trades worker.
As assigned a Mason and Plasterer will supervise other trades positions including other Mason and Plasterers and subordinate employees and/or wards of the State in making assignments, giving instructions, and observing and inspecting work performed to insure that instructions have been followed and that the quality of the work is satisfactory.
