Mechanics at Northwest Airlines are vowing to continue their strike, even as the airline says it has begun hiring permanent replacements.
With the walkout in its fourth week, about 200 mechanics rallied at the union's strike headquarters near Minneapolis-Saint Paul International Airport.
The two sides haven't met since early Sunday, when mechanics walked away from an offer that sought even more concessions than they rejected before striking.
In a letter to the union late yesterday, a Northwest executive urged union leaders to allow a vote on the airline's latest offer.
Union officials have said only a handful of mechanics have crossed the picket line.
The mechanics' union got a financial boost today from the United Auto Workers, which donated 880-thousand dollars.
