Here is an excellent article, written by Richard D. Kahlenberg in the American Educator magazine by the AFT (America Federation of Teachers) Volume 39, no. 2| Summer 2015. In it, Kahlenberg details the history of unions and why due process is so important to maintaining high quality teaching that is inclusive and free of politics. Indeed, tenure is a fundamental aspect of "workplace democracy" (Kahlenberg, pp. 8). This is an excellent read for those of you that want to understand the reason why teachers should be unionized and have tenure.
