"Craftless" is an adjective that describes a person who lacks a specific craft or skill used in a job. It is derived from the word "craft," which means a specialized skill used in a vocation. Someone who is craftless may have a hard time finding high-paying jobs.
A craftless person is less likely to belong to a trade or professional union. "Craftless" may also describe the nature of the work as opposed to the person himself. A craftless job is one for which the employee does not need special skills. A worker at a manufacturing plant who operates a simple, basic piece of machinery might not need a craft, for instance.
