The DEC President who pushed those endorsements was voted out. Based on what they posted on Facebook in the last few days, I think DEC is seriously planning for a strike; this is part of a post from yesterday:

"While DEC understands D65 is in real financial trouble, DEC doesn’t feel the problem should be solved on the backs of the educators. Let us be abundantly clear, ever since we began financial negotiations, D65 has been transparent in that they are hoping to solve their financial woes and mismanagement by balancing the budget on our backs, while refusing to accept or acknowledge their own administrative excess."
