I have several newer people on my crew. They are great workers. They are mainly encapping MILES of cgd each week and doing some very basic spotting. I want to give them some more training but just trying to figure out the best direction to go and how to go about it. Mainly I want to teach them more on spotting. Should I go into fiber identification? We literally have only one wool carpet we clean. Or just go straight into showing them how to use a full spotting kit? And should it be on the job or take out a few hours to commit to training?
