My previous situation. Both parents elderly with health needs, supported by carers and myself. If one went into hospital, extra support was needed as I couldn't be in two places at once. Other family was supportive and stepped in, but had their own commitments too.
One parent had a surgery scheduled, so we paid for a lot of extra carer support for the other one. Cancelled services such as Day Groups for the first parent.
Surgery was cancelled too late to cancel the carers without us having to pay. Parent couldn't attend Day Groups so missed out on socialising.
A lot of expense and inconvenience, not only for my elderly parents but for the wider family too.
This happened TWICE (for the same surgery).
Sadly, this isn't an isolated incident. Many people, of all ages, are being severely impacted by these cancellations. Young families can have lost wages and extra childminding costs for example.
