Does any airline out there offer "snap back" anymore? This is new to me, but my regional is also ghetto.

I know a friend who had a class date at a major so he quit my regional. On the day of class, he found out class was cancelled. He didn't get called back for years! When I finally get the chance to finally move on, rest assured i will be giving 2 weeks notice (no more), and there will be overlap of at least a day so I can always have the option to g back to my previous employer.
