It's well known in ARAZPA that they have a large staff turn over, and most that have left tell the same story. " that they couldn't work for a family that won't listen or that they were asked to go because they stood up to one of the family.
I know that one Curator that put together the collection was asked to go when he had words to one of the family about the way she was talking down to the keeping staff and that she herself had very little runs on the board when it came to working with animals. and that she was only records keeper because daddy owned the zoo.
many staff that have left came from afar (New Zealand, Perth) being told that they would be looked after only to find out that this wasn't true.
