Mayumi Shinde, 40, has worked for seven years as a system engineer at a Tokyo firm, at one stage attaining a job capability assessment of S -- one special level higher than A, the normal top ranking.
After taking child-care leave in December 2000, however, Shinde saw her ranking at Data Communication System Co. immediately downgraded to the lowest scale, causing her annual pay to drop by 1 million yen.
