This fonds contains oral interviews gathered on the subject of labour history from the view of Mennonite business owners and Mennonite employees and well as the history of Westgate Mennonite Collegiate in Winnipeg. The workers were selected from different gender and social classes. The content formed the basis for Thiessen's thesis on labour history of Russian Mennonites, a book on unions, and history of the private Mennonite high school, Westgate.
