i dont really know if it was her idea or not to leave, she seemed fine, but i didnt hear back from her, just her mum.
As she was only 16 at the time we did make sure she was never working alone, made sure she understood her job etc. We felt that we had a bigger responsibility towards her as she was so young. She has worked before, and i had references from her old jobs, she recently moved to the area (her parents were from here originally).
The excuse was that they didnt like the idea of keyholding, and collecting/returning to the office. (they live 10 doors away from me in the office), perhaps the evenings werent suited to her after all. 5-8pm.
