The United Auto Workers union says the UAW GM National Council has approved a tentative labor agreement with General Motors Co. (NYSE: GM). The agreement must now be ratified by local UAW members nationwide and the union says workers will remain on strike until ratification.

Informational meetings and votes will begin to take place Saturday, according to the union, and continue until October 25. 

"We thank the public for their support during the strike and their continued support as UAW GM members review the tentative agreement," UAW Vice President and Director of the General Motors Department Terry Dittes said in a news release. "Ultimately, UAW members will make the decision to ratify the agreement. Their unity and solidarity brought us to this moment."

UAW GM negotiators announced Wednesday it had reached a proposed tentative agreement with the automaker after five weeks of negotiations. More than 49,000 workers have been on strike during that time, including some 7,000 in Indiana.

GM has four Indiana facilities, located in Fort Wayne, Bedford, Kokomo and Marion. The state is also home to a number of GM suppliers.
