Construction workers can add to their value
Why not take a few online courses to make yourself more valuable to your employer. I believe that you might even get them to pay for the course fees and the LEED certification exams if you tell him how much more valuable you will be to him, and that you would work for him and do inspections on the green buildings who need to be rated. They will be happy to have one of their own people available whenever they need them to get advice with constructing and converting the buildings for better energy consumption and other things that are pertinent to getting them rated high on the scale.
