Most places I know of a journeyman's book in the construction trades (Pipefitters, Boilermakers, Millwrights, and Ironworkers) is akin to a master key for entry into industrial maintenance. And this with a strong bias towards those who have graduated an apprenticeship in their trade.
And It's not like any tradesman can do any job when he walks in the door, but the journeyman's book, and documented work history show evidence of work ethic and ability to learn. Use the master key for entry. Work and learn to master a new job.
