Lesson activities to accompany the vignette "Trouble on the Line” from the acclaimed Knowledge Network series; Working People: A History of Labour in British Columbia produced by Landrock Entertainment. The vignette explores the role of female telephone operators in British Columbia and their activism that contributed to the first strike in the Canadian Telephone industry. The supporting lesson materials focus on the role and challenges that women had in creating a voice and place for themselves in the early telephone industry as well as their role in shaping the early union movement in the province. This is a unit created by the Labour History Project, a group of retired and current British Columbia teachers collaborating to develop a series of lesson plans, activities, and workshops focused on labour studies and labour history.
