Leaders of Boeing Co.’s striking Machinists union on Thursday published details of a contract offer it says protects more than 5,000 factory jobs, as workers expressed mixed opinions about the tentative deal.

The organization posted the latest changes to the proposal from the airplane maker on its Web site and recommended that the roughly 27,000 union members accept the offer in a vote scheduled for Saturday.

“The revisions … provide job security to over 5,000 members that Boeing otherwise could have replaced with vendors and contractors inside the factory gates,” the International Association of Machinists and Aerospace Workers said in a statement.

A union vote to accept the offer would end an eight-week labor standoff that has eroded Boeing’s profits and delayed deliveries of its commercial aircraft, including its long-postponed 787 jetliner.

Workers at plants in Washington state, Oregon and Kansas are affected.
