Based on speeches presented to the National Civil Service League and to the Washington Suburban Sanitary Commission, this article reviews key publications and summarizes Federal statistics on part-time employment. Review of the evidence concerning the effectiveness of part-time workers shows positive results. The need for collecting hard evidence is demonstrated and areas in which research is needed are described. The paper identifies barriers to the expansion of the part-time scheduling concept, describes jobs that might be performed on a part-time basis, and shows how part-time employment fits into the personnel ceiling system. The advantages and disadvantages of part-time employment to both managers and employees are stated and comparisons with flextime made. (Author/WL)
