The effects of an in-house workplace literacy program on an organization are examined. A small Canadian manufacturing plant that began a workplace literacy program called Learning in the Workplace in 1990 was the site of this case study research. The plant was CCL Custom Manufacturing, which specialized in household powder-based products. Four areas were explored: (1) the effects of in-house literacy programs on improving the basic skills of the members of the organization; (2) the effects of peer tutoring in the workplace; (3) the effects of organizational events on in-house workplace programs; and (4) the effects of partnerships in workplace literacy. The research indicated the following: an in-house program helped members of the organization improve their basic skills; peer tutoring was a catalyst to opening up communication channels across the organization and building workplace relationships; a stand-alone program was more vulnerable to organizational change than programs integrated into the training culture of an organization; and a workplace literacy partnership strengthened the program.
