Did you really just compare the job of the ref to the job of a bus driver? BTW...the refs are independent contractors...they are not employed by anyone. If they were, we could fire them.
In the limited sense that a significant portion of the job involves concern for the safety of the children in their care, yes I did. It is perfectly legitimate in argumentation to construct limited analogies.
They are independent contractors, yes, but so are many coaches, and I responded to a comment regarding coaches' acting like adults. So, what's the problem?
