Union apprenticeship programs blend structured on-the-job training with relevant theoretical education, typically sponsored by labor and management organizations, as well as employer groups capable of providing both hiring and training opportunities in a real-world work environment.

Apprenticeships generally last between three to five years, enabling participants to gain valuable experience, while learning the necessary skills in their chosen field.

These programs are designed to prepare individuals for skilled employment by offering training in legitimate and documented workplace settings. The specific content of both on-the-job training and related instruction is tailored to meet the needs of particular occupations within various industries.
