Entry-level union jobs are often found in construction, manufacturing, and general hard labor industries. Tradespeople, public works employees, and other professionals may also have union membership. Many entry-level union positions are apprenticeship opportunities or on-the-job-training opportunities. During entry-level employment, you learn a trade alongside experienced workers. Your duties and responsibilities vary depending on the industry in which you work, but you always work under the supervision of a more experienced professional. As a union member, you pay dues to the union, which works to negotiate with the employer or management to arrange a collective bargaining agreement.
