Some 300 seasonal and former temp workers of Isuzu Motor Co. and union members held a protest Wednesday in front of the company's head office in Shinagawa Ward, Tokyo, claiming their right to work to the end of their contracts.

Major truck company Isuzu announced Dec. 24 that it would not cancel the contracts of some 550 seasonal workers following union negotiations and the government's request to maintain a stable employment situation.

Originally, the company had planned to lay off around 1,400 temporary and seasonal workers by Dec. 26 at two factories, in Fujisawa, Kanagawa Prefecture, and in Taihei, Tochigi Prefecture.
