Apprentice Engineer. An Apprentice Engineer works under the direct and immediate supervision of a Chief, Assistant Chief, Senior or Journeyman Engineer. This classification is distinguished from that of the Watch and Maintenance Engineer not so much by the work performed as by the supervision received. This is strictly a trainee classification. An Apprentice shall not stand a shift or in any way be responsible for operating conditions in the plant. During the apprenticeship period, the apprentice shall be subject to the terms and conditions of the “Apprenticeship Standards of the Operating and Maintenance Engineer Trade for Southern Nevada,” which provide that he shall receive such instruction and experience in all phases of the work as are necessary to become a practical and skilled mechanic versed in the theory and practice of the Operating Engineer Trade. Apprentices shall also perform such other duties in the shop and on the job as are commonly related to such Apprenticeship. Candidates for Apprenticeship shall be selected in accordance with the Rules and Regulations promulgated by the Nevada Apprenticeship Council and the Apprenticeship Selection Procedures of the Apprenticeship Standards of the Operating and Maintenance Engineer Trade for Southern Nevada.
