Three former employees of Goldman Sachs Japan are willing to take legal action if they don't get their jobs back or the company doesn't negotiate in good faith, a spokesman for the three said.

"They terminated our employment without cause and justification. They acted in bad faith, pretended to negotiate but did not really negotiate," Timothy Langley, a supporter of the three, said in Tokyo at the Foreign Correspondents' Club of Japan. Langley, who is not a attorney but has studied Japanese laws, is providing them with legal advice.

The feud adds to the investment bank's publicity troubles after former Goldman Sachs employee Greg Smith recently criticized its corporate culture in a New York Times Op-Ed piece and caused a stir in the financial industry.
