Long accustomed to being ignored, being forgotten proved too much to take for unionized teachers at Gaba language school. On Oct. 4, the General Union registered an official complaint and request for an investigation with the Ministry of Finance's Securities and Exchange Surveillance Commission (SESC).

The union accuses Gaba Corp. of lying in its 2009 financial report filed in March with the Tokyo Stock Exchange, which states that there is no union at Gaba and that labor-management relations were "smooth and harmonious."

The G.U. argues it has an established Gaba Branch. Its complaint also points out that the Osaka Labor Commission ruled in December 2009 that it considered earlier negotiations held between the union and Gaba to represent collective bargaining.
