From the Aug 2 MEC message:

Your Negotiating Committee is working with the goal of completing Tentative Agreement (TA) language by the last week of August. Upon completion, the agreement will be sent to MEC members to begin their required 7-day review process. Soon after MEC receipt we plan to send you the TA, along with links to supporting educational materials, to allow for discussion and input.

A special MEC meeting to consider the Tentative Agreement will likely be scheduled for September 6-7. If the TA is accepted, balloting will open on September 8th. Voting will likely close on the morning of September 29th to comply with MEC Policy’s 20-day requirement. If the TA is ratified, the Date of Signing is planned to occur on or about the beginning of the October bid month.
