Senator Ulick Burke mentioned the withdrawal of discretionary posts. As Senators who worked in the teaching profession are aware, there is a good appeals mechanism for such posts at second level. Most cases are dealt with fairly, as Senator Fitzgerald said. I take Senator Ulick Burke's point about the science subjects because physics and chemistry should be part of the school curriculum in a modern country such as ours, although there has been a falling off in the number of students studying them.
