If you can show me a county in which this was not the law before the Clerk volunteered to work in this county, then you will have a valid point.
If you know of no such county where such a change has occurred, then you do not have a point.
Changing the accepted understanding, and the conditions consented to by the employee requires at the very least a re-negotiation of the implicit contract.
Once again, I will quote Abraham Lincoln when he was questioning a witness.
"Suppose you call a tail a leg. How many legs would a sheep have"? The Man replied "Five." Lincoln said "No, only four. Just because you call a tail a leg, doesn't make it so."
