As a union lineman, your job is to help install and repair electrical equipment used by local utilities. In this role, you may help monitor the power levels of an electrical grid, help with the construction of new connections, and otherwise support the daily operations of electrical systems. Union linemen often shorten or lengthen lines, dig holes, climb utility poles, direct traffic, and drive specialized vehicles. Some union linemen also use computers, maintain tools, and perform other tasks as needed to get each job done. Union linemen normally work predictable hours, but employers may ask you to work extremely long shifts after storms or natural disasters.
