Do you “call in sick” or “call out sick”?

[EGM92]

Call in sick - eastern Canada, like sane person would.

 

[Servbot24]

I'm down for that
I'm up for that

^ I say both of these routinely and they mean the same thing

 

[MaulerX]

If I'm making the call then I "called in sick". If I'm at work and receive the call from somebody else then I say he/she "called out sick".
