When I was there, the school only employed staff who were Catholics. However, that policy has seemingly changed as I know someone who teaches there.
I don't know how that change came about, but I imagine it would be discriminatory to not to empty someone on religious grounds.
Catholic schools haven't been allowed to only recruit Catholics for at least a couple of decades. Some might put limits on what a non-Catholic can say if they're in a post where they'll, for example, be teaching sex ed, though. Some are more open to free discussion in that respect than others.
I have O-level RE, btw. The only senior school in my town was CofE and "Jesus" Jones, head of RE and local clergyman (and all round sound bloke, to be fair), insisted that, as top set, we were wasting our time unless we took the exam, since we had to do the lessons, anyhow.
