Agreed for her to take care of our 1 year old three afternoons a week for the foreseeable future. We left it flexible for her, as she was actively looking for a full time position - and we accepted that she would jump at one if it came up. But we agreed - and she was in fact quite adamant - that she would give us at least a week's notice, and not leave us scrambling for a nanny with no notice (as both of us work full time). So we went ahead and rejected other nannies and - at her request - even paid for a temporary residents parking permit for her.
Then, right before her first day, she did exactly what she said she wouldn't do. She didn't even call, she texted, with some far-fetched excuse about a friend being in a car accident and her having to quit all her paid jobs immediately, so she could look after her friend's children.
We would have had a lot more respect for her if she just told us she had found the full-time position that she had been looking for, and had to start straight away, or if she told us she didn't want the job in the first place. At first glance, she certainly looks like an experienced childcarer, and presents herself well. However, we couldn't help feeling seriously let down, and that she wasn't reliable enough to care for our child.
On the positive side, she informed us that she doesn't smoke, likes animals and seems fine with children.
