Apprenticeship: Building Your Career

LaborEd Minnesota
Published on Dec 13, 2012

The Labor Education Service and the Apprenticeship Coordinators Association of Minnesota produced this video to promote recruitment to the apprenticeship programs of various trades in Minnesota. The video reflects the changing demographic pool of apprenticeship applicants over the past few years- not only recent high school graduates, but also the increase in the average age of applicants, and in those seeking mid-career changes. This pool also reflects the diversity of applicants that the trades and the construction industry want to attract. One of the main themes of this video is to promote professionalism in the trades. The program features workers on the renovation of the historic Union Depot in St Paul as it returns to its earlier glory as a transportation hub for the Twin Cities, the state of Minnesota, and the upper Midwest region.
