I'm a live-out nanny and will start a job for a new family soon. I've been recently asked what I usually have for lunch. In my previous jobs I brought my own lunches from home although my contracts included lunches provided by employers. I simply didn't want to have a toast with marmite for lunch every day. This time I would like my new employers to provide my lunches as everything is getting more expensive and my wages are the same as they were 3 years ago. I will be looking after a baby so I will not have the same food as him. Can I buy my food and ask for a reimbursement?
