I work in primary supply and have been given a 12 week contract. However there are several issues that I am not happy with - I am told that they are the worst class in the school but am given no support with the behaviour issues. I have been abused by a parent, but it is brushed under the carpet. I really don't want to stay but feel it won't look good if I leave. I am already registered with other agencies but not sure whether I will appear to be unreliable. Any advice/comments?
