The United Auto Workers union said on Wednesday that it had reached a tentative labor agreement with Chrysler LLC ending a strike against the automaker on the same day it began.

The UAW said in a statement it was calling off the strike against Chrysler effective immediately.

UAW President Ron Gettelfinger said in the statement that the tentative agreement would protect wages, pensions and health care for UAW-represented Chrysler workers and retirees.

Details were not immediately available.
