  • Tell Me A Story Using Narrative to Teach Safety to Skilled BlueCollar Workers
    Tell Me A Story: Using Narrative to Teach Safety to Skilled Blue-Collar Workers
    Cullen, Elaine T.
    2023/03/01 | Mining Publications
    Miners, like many skilled blue-collar workers, are not traditional learners. They have not generally been successful in classroom-type settings, preferring to learn on the job in a hands-on environment. U.S. miners are required to have annual safety training, but they rarely view this positively. In fact, it has been called safety jail by many of t ...
