The United Auto Workers union has a tentative deal with General Motors, the last of the Big Three automakers to come to an agreement, four people familiar with the situation said Monday.

The move could be one of the last steps to fully ending the autoworkers’ strike, which has gone on for more than six weeks.

President Joe Biden, asked about the deal Monday morning, said “I think it’s great,” and gave reporters a thumbs up.

The union in the past week reached tentative agreements with Ford and Stellantis. Like the Ford agreement, the GM deal includes a raise of about 25 percent over a four-and-a-half year contract, according to two of the people with knowledge of the development. All three deals still need to be ratified by union members.

GM declined to comment.
