Yes, exactly, employees may not actually be like virtual servers that you can spin up and shut down at will, but some employers will think of them that way.
Some employers? That seems to be the norm from what I've seen. Team leaders usually know full well how hard it is to find good new people and get them trained, just like the previous comments here say, but somehow upper management never seems to understand this at all. I guess they think that's lower-level management's and HR's problem to solve.
