Hello,
This link will bring you to a free Web-based Powerpoint-type presentation to learn about the history of the CBTU. You have the choice between a US or Canadian version. The US version was adapted into a DVD which circulated at the CBTU International Convention in May 2012. If you were looking to learn about CBTU, or to teach other union or community groups about what CBTU does, feel free to use this free presentation material.
