Finding itself at the center of highly publicized legal and political deliberations over fairness in testing, personnel credibility, and legal liability, the training department at a North American transit authority adopted a genre system that enabled the production of objective evidence of job competence, which was then used to make objective decisions about who passed and failed various training programs. The ongoing genre-structured activity of the department involved not only the regularization of organizational texts but also the regularization of social interaction mediated by those texts, which, while producing the types of interpretively stable documents required for successful public deliberation, led to a shift in authority and social relations within the department that instigated considerable resentment and loss of morale among many veteran instructors.
