Is bailing a checked swing?

I should add that when I am working with a somewhat "weak" partner who I may or may not trust to make the right call, I cover check swings in my pre-game with them, and tell them how I want it called! I explain that they can call it any way they want with other partners, but would prefer for this game for them to call it the way I do. This sort of get's around the problem of them thinking that somebody else's interpretation is the proper one.
