The Nippon Telegraph and Telephone Corp. group [a company one third owned by the Japanese government] failed to pay to the state a portion of pension premiums of about 4,000 employees over more than six years to August 2003 despite deducting the money from the workers’ salaries.
Sources attributed the failure to clerical errors. The group has already filed a request to a government third-party panel that the pension records be corrected to ensure the employees receive the benefits they are entitled to, officials said.
According to the sources, discrepancies were found between pension records maintained by the Social Insurance Agency and those at the group’s employee pension fund. No records were held by the agency for about 20 short-term contract workers.
