A caregivers certificate was not accepted as a suitable qualification during the time when it was possible to get work permits for carers from the Philippines. It was also not possible to employ someone with a nursing qualification, on the grounds they were over qualified! Those that were accepted held other "medical" qualications, and I employed midwives, PTs and clinical physcologists. All that has stopped. However for someone legally in the UK through marriage and seeking work I think caregivers training will help an applicant, as will simply being a Filipina, because of the well known reputation they have for being carers. Good carers are not easily found and I have no doubt at all that this lady will find a choice of work open to her. Whether she will be able to get £7 per hour depends on the locality and the availability of carers there. If working full time she will be given 24 days per year holiday, proportionate if part time. UK public holidays are NOT in addition to that entitlement, so if she is off on a public holiday it will count towards that annual leave. There is no general entitlement to a "13th" month christmas payment in the UK. Some businesses do operate that way but generally for staff on salary, not on a wage. I have never seen it in a care home.
