I'll say what I always say, which is that until the care sector evolves into a profession which respects its employees, it will continue to provide bad care to the vulnerable people who need it (& pay for it a lot of the time).
OP, I suspect you are good at your job, but I also suspect you give good care to your service users in spite of the system.
Carers deserve respect. With career progression, a reasonable pay scale, hours, contracts, holiday and sick pay, pensions etc.
As a disabled person who relies on carers to survive (direct employees, not agency), I have have appalling abuse at the hands of carers, and also seen carers on the edge of break down attempting to do right by the people they care for in a system which has zero respect for carers or those that need care.
It's a sick system, and I hope one day it changes, for everyone's sake.
