Within the IBEW, what does "seniority" refer to?

The concept of "seniority" in the context of the IBEW primarily relates to the length of time a member has worked within the union. This measure of tenure can significantly impact various aspects of a member’s career, including job security, promotions, layoffs, and the selection for better job assignments or overtime opportunities. In many union agreements, those with greater seniority are prioritized in cases of job availability and other employment-related decisions, thus establishing a clear incentive for members to remain in good standing and continue their employment.

While attendance at union meetings, specific skills, or the age of a member may have some relevance to a member's involvement or qualifications, they do not affect the fundamental nature of seniority as it pertains to job status within the union. Seniority is recognized as a critical factor in labor relations and collective bargaining, aimed at protecting and enhancing the rights and opportunities of the members based on their duration of service.
