Smithfield Foods says more than half of its five-thousand employees have signed letters asking a union trying to organize the plant to allow a vote.
The United Food and Commercial Workers have been trying for more than a decade to organize the world's largest hog slaughterhouse, located in Tar Heel.
Smithfield officials say they offered employees letters addressed to the union's president asking for a vote. Nearly three-thousand of the employees signed the letter.
Union activists have opposed the company's strategy and have called for card-check organizing, which would force the company to recognize a union if the group can get more than half of employees to sign a card. They say it's the only way to ensure the company doesn't cheat the elections.
