I've just started a very short supply stint - less than a week - at a school. However, the children I'm teaching are a really, really difficult class. Difficult as in the business manager told me shortly after I walked in that they were really difficult and not to take it personally. I perserved with the day, but I found it amazingly tough and called the agency. They said they'd had no heads up about this issue, but this school was new to them. I've worked at about forty different schools, and while I've had difficult classes before, there have only really been three that I said I wouldn't work at again. I've already tried various strategies to no real avail. I told the agency that I'd let them know mid-day tomorrow if they needed to get someone else for the remaining days. Thing is, I have mixed feelings about this. Should I see it through or back out when I call the agency tomorrow? How would that reflect on me? Has anyone found themselves in the same situation? What did you do?
