The availability of projects is affected by the seasonal nature of the construction industry and by economic conditions that affect construction activity. Working conditions will vary depending upon the type and stage of the construction project. Rough wiring is done before walls are in place and is weather-dependent. Later in projects, the installation of electrical equipment is done indoors. Much electrical work is done in a standing position, often in confined spaces.
Physical risks involved include falling from a height or receiving an electrical shock.
This lower earnings level indicates that a high proportion of women electricians are new entrants to the occupation. Although this occupation has traditionally been highly unionized, current trends are moving away from union positions. This occupational group experienced a decline in workers, from 5,960 in 1990 to approximately 5,500 workers in 1998. This occupation is still a large occupational group despite the small decline in workers. The International Brotherhood of Electrical Workers estimates that there are more workers in this group, but the union groups electricians, industrial electricians and power system electricians into the same category.
