This deal looks a lot like a face-saving way for the IAM and the NLRB to give up.
This is a victory for conservatives. The National Labor Relations Boards (NLRB) attempt to dictate where businesses invest has failed.
the IAM knew the courts were very unlikely to shut down the South Carolina plant, while the NLRB itself will soon lack a quorum and ability to act.
Obama would have a difficult time defending it on the campaign trail. Todays contract allows the IAM and the administration to back down without formally admitting they made a mistake.

I think you're right on the money. That coupled with the comment in post #11 made it easier for the IAM and NLRB to fold.
