I do not believe they have ever had one. They have been represented by the Teamsters longer than AMFA.
SWA has never had lay-offs. Although they have had early retirement encentives along with buy-outs to reduce the number of employees. Some people, as I have heard, say they feel that this is a form of rif's, and it is not. Generally when your riffed it is not by choice or with a buy-out package as well as they all get to keep their bennies as long as their numbers add up (you know age and service years).
Rumers on the floor are flying that folks are hearing of another early-out like "Freedom-09" Some are saying it will be when all the dust settles from transitioning AT into SWA, so maybe a time frame of 2-3 years, who knows.
