Contrary to what people may think, the most humane way is a fast clean cut. Drawing it out in anyway doesnt help anyone. This does assume communication is clear about employee next steps for HR related tasks.
This is also why in the other direction a fast clean cut works too. I mean if they want two weeks of “work”, i always consider that severance.
The fast clean cut is true in all industries. Drawing it out only makes it more painful. It is similar to breaking up in a relationship.
It sounds as if you're describing how to humanely kill a living being.
There are alternatives to killing things and I don't think fast clean cut is true in all industries. I think people want it to be true because then it hides away the complexity of the emotions we feel. Just cut it off and pretend that the cutting off won't bother us or them after the event.
I think that strategy may appear helpful but just buries most of the feelings, which don't go away, most likely just to fester underneath and erode trust.
