This annotated bibliography of New Zealand trade union literature includes human resources, labour studies and social history. It is more complete and up to date than Bert Roth's (1970, reprinted 1977) bibliography, and much of the material does not appear in Austin Bagnall's 'New Zealand National Bibliography'. Other than trade unions themselves, political and union activists, social historians, students and book researchers will find 'Words at Work' a valuable resource. Even a cursory glance at the wealth of literature, covering 130 years, recorded here shows a broad range of diverse activity across many occupational groupings, windmills that have been tilted at and often bent, the indefatigable nature of worker organisation and action, and the striving for progress in areas of life beyond the industrial.
