The Continuing Education of Employees. a Review of Selected Policies inOntario. Informal Series/8 by James A Draper( Book )

1 edition published in 1978 in English and held by 1 WorldCat member library worldwide

A study to examine policies governing educational assistance plans for hourly and salaried employees in selected nongovernmental organizations in Ontario is reviewed. In the first of five chapters, educational assistance is defined as tuition aid and paid/unpaid educational leave plans to assist employees in pursuing education and training through outside educational institutions and agencies. Chapters 2 and 3 summarize some developments concerning educational assistance systems for workers in selected Western European countries and in Canada as a context for analyzing Ontario's educational assistance practices. The final chapters present the results of a content analysis of educational assistance policies from personnel manuals of twenty-one private companies and from eight collective bargaining contracts in the private sector. The nature and frequency of the various entitlements are described, and policy models and critical provisions are identified. (Css)
