> So leads me to wonder if this should be some sort of emergency switch like an IFTTT trigger or something that triggers the deletion of certain things on certain devices should I trigger the emergency switch.

Wouldn't take much for that to be misunderstood and for you to get a nice friendly visit from the cops. YOU might know that it only deleted "your" stuff. But your employer might not.

I agree with everyone else in this thread: Stop leaving stuff on work computers. Period. You use a password manager, log it out every single day. You want access to files? Install e.g. DropBox but log in every single day, etc (or use your phone as a USB storage device).
