Well I understand it, but the analogy I was trying to illustrate is that in theory, 10% of a workforce produces something, and while it costs something to employ them, it also costs something to lose their employment. In theory. Otherwise, why were they hired to begin with?
There are inefficiencies in every organization. It's not like 100% of the workforce is 100% productive and critical to operations. You can cut a lot more than 10% before it starts to affect the business in a meaningful way.
