Does anyone in the union realize a strike benefits Boeing right now.
They are unable to deliver aircraft due to parts and faa restrictions. All a strike does is give them a chance to get the parts in, it let's them out of penalties for late deliveries.
Boeing is likely to save so much money from waiving penalties for late deliveries, a 40% raise will look like pocket change.
Boeing is hoping and praying for a strike. And the union is just d-mb enough to give it to them.
The best negotiation tactic would be "give us what we want, or we will accept the first offer and you can deal with angry customers"
