This report examines the wages and quality of a sample of new hires by large firms (over 500 employees) over a period of seven years. In manual occupations workers with fully qualifying work experience were found to receive entry wages not significantly different from entry wages received by workers with no previous work experience. This placed the inexperienced, less productive workers at a disadvantage and it was found that the proportion of inexperienced workers in the total of new hires decreased when the total number of hires decreased and when the supply of experienced workers increased. In clerical occupations a larger degree of wage differentiation with respect to previous experience was observed and no systematic relationship obtained between the proportion of workers of various skill levels and the number of new hires or the supply of experienced workers.
