In fact, it appears now the school I have applied with called the office of the school where I was volunteering and, asked to speak to the person I named as reference (quoting her name). As she was not available their call was, without them knowing (!), then transferred to the headteacher who answered their questions. As surprising as it is, the headteacher at the school willing to employ me is therefore convinced she spoke to the person I named as reference. I called her and explained the situation. She spoke to their human resource department but, there is nothing she can do as the decision to withdraw the offer has already been taken and someone else been employed. I have also got in touch with the person I named as reference. She was not aware at all that someone tried to get in touch with her to obtain a reference for me (she knows I am using her as reference). I have called the headteacher who gave them the bad reference. She refused to discuss the matter with me. There were no investigation. I once went to this headteacher office to ask if I could set up an after school club and, she told me then that two months before a child came to her to complain about me. I was shocked as, she didn't bring the case up at the time where the child came to speak to her and, no one ever mentioned such allegations (once again: I have learnt about it two months after, while going to discuss a complete different matter with her). Of course, I have denied everything. In fact, I even didn't give it any other thought as this headteacher told me then that everything was alright, she had dealt with it and the pupil in question. As she never questioned my volunteering in her school, never complained to the College with which I was then doing my Level 2 Teaching Assistant and, even, later employed me as Lunchtime Supervisor I believed she clearly believed such allegations 'bogus'.
