That's exactly the situation in relation to rostering! Though it does seem as if a shake up is happening currently, and every time I speak to them there is a new person around, we'll see what happens.
Your point about Emerald always being a stepping stone is valid up to a point. For many, it will always be just that, but some have no intention of moving on, particularily in Liverpool.
I object to the way all the staff are treated, just because they aren't expected to stay for very long, but, if people were trated in a non-bullying manner and with some basic respect, then the issue of staff turnover would be greatly reduced, especially amongst the Op's bods, who quite frankly have an almost impossible task on occasion.
