Untrustworthy and dishonest
Unfortunately I had a very bad experience with Jenny. She was my nanny for three years, with a break in between for medical reasons. When she returned she failed to provide suitable supervision for my child and also charged me for childcare hours, which she never worked. Once I discovered what had been happening I asked her to leave. She was extremely unprofessional in the process and I would caution anyone looking for a reliable nanny to take proper references and ask for a DBS check.
