The Machinists union is still mulling over the “best and final” contract offer the Boeing Co. delivered yesterday.

Union leaders posted an update at 2:30 a.m. asking members to be patient.

“We need to understand every clause before formulating our recommendation so we can present ALL the facts,” they wrote.

The Machinists are printing copies of Boeing’s offer for the 24,000 members here in the Puget Sound region to read. Union negotiators will post their recommendation whether to accept Boeing’s offer by the end of the day.

Boeing posted the text of the contract at its negotiations Web site.
