I put, "She employs about one hundred staff" and it was wrong. In a previous question "personnes" to "staff" was allowed. Why not here?
sean.mullen: Even if you asked your question about three years ago, I'll try to answer it today (A Frenchman would say: 'Mieux vaut tard que jamais'). You ask me how to translate plural "staff". It could be possible to say : "Il y a, dans cette entreprise, environ cent MEMBRES du personnel". I hope, my answer doesn't come too late.
