The labor union of Nippon Telegraph and Telephone Corp. for a second consecutive year will not seek a uniform hike in base wages during spring salary negotiations, union officials said Wednesday.

"We want to put the greatest priority on securing employment and stability," said Junjiro Tsuda, head of the NTT labor union.

The decision by Japan's largest private sector labor union, which has around 210,000 members, will be formalized at the union's central committee meeting Friday, the officials said.
