On the changes in the law to raise the re-employment age to 67 which will take effect in two to three years, SMU School of Economics Associate Dean (Faculty Research) and Professor of Economics Hoon Hian Teck said that some firms are reluctant to re-employ older workers above 65 as the productivity of the workers may not match their salary expectations. "The Government can step in to subsidise part of the wage cost during this transition phase before legislation kicks in," he said.
