I think it is a good job, there are many people that need care in this rat race part of the world called the UK, it is too crazy here to look after our own elderley people, so we get others to do it, and yes a lot of British would not get out of bet to do it for the wages offered.
I congratulate you on getting a job and working in the care industry and wish you and your husband well for the future.
My Wife also started work in a care home, working in the admin office and my mother worked in care homes for years, it is a honourable job :-)
As others have mentioned about bum wiping just think of the Caregiver Film as she says when a puwet needs wiping, think of pounds :-)
Keep up the good work....
