It took nearly five years of legal wrangling, but 15 workers in the auto services department at the Wal-Mart supercenter store in New Castle are getting an opportunity to vote on joining a union.

The National Labor Relations Board, in a case that has been pending since 2000, has scheduled an election for Feb. 11 to let employees of the store's Tire & Lube Express department decide whether to join the United Food and Commercial Workers union.

It is the only pending union-representation election at any Wal-Mart in the United States, according to the UFCW, which for years has unsuccessfully sought to represent Wal-Mart employees in stores across the country.

The New Castle election originally was scheduled for the summer of 2000 after the labor board ruled that the tire department workers were an appropriate voting unit.

Wal-Mart had argued that the vote should include the store's total work force of more than 400.

But the 2000 election was halted when the UFCW's Cleveland-based Local 880 filed unfair labor practice charges against Wal-Mart, alleging the giant retailer interfered with the election. The union alleged Wal-Mart executives from Arkansas descended on the store immediately after the election was scheduled and improved conditions for the auto service department workers.

The company installed new equipment and, the UFCW argued, engaged in surveillance of employees' union activities, interrogated them about their union sympathies and moved various employees in and out of the department to dilute support of the union. The allegations were settled by the board in an unpublished ruling late last year, paving the way for the next month's election.

Wal-Mart, which as part of the settlement was ordered to cease the offending practices and inform employees by posting notices in the store, declined to comment yesterday.

UFCW spokesman Greg Denier said Wal-Mart's actions at the New Castle store were typical of tactics used over the years to keep the union out.
