Part of the email the MEC sent last month

“Should Spirit determine they are unable to comply with the terms of our CBA, we expect that they will seek a negotiated solution that will need to be ratified by the entire membership.

Unfortunately, there is no way to avoid the displacements. We cannot simply tell them “no” or refuse to participate. This is their business to run, and they have determined that for the enterprise to succeed, they need to add crew bases and “right size” others. What we can and will do is ensure that your rights under the contract are protected.”

So strap in for the “we are going to present for a vote a compromise with management to reduce the number of involuntary displacements by agreeing to…”

They essentially told us the company is going to do what they want and they will seek a “negotiated solution”.
Depending on the terms, if it prevents mass forced displacements while providing for compensation for the pilots, the MEC has to at least listen to it.
