i think that it depends how proactive bosses/owners of the business whether carehome or care agency are about training their staff and how much of a priority they think it is.
my own experience - i was paid minimum wage which increase only when the minimum wage was increase. this well below the living wage. i was expected to do everything, personal care and anything that the residents needed including medication administration, cleaning, laundry, cooking, washing-up and clean kitchen, make sure residents are eating and drinking and to write a log of what the residents have done/refused to do, how much eaten/drunk, any medical visits and toilet patterns.
i had 6 hours along with the other carers and its hard work. all that needing training and there is also mandatory training, health and safety, safeguarding, challenging behaviour, infection control, moving and handling properly along with other relevant training EOL, meds admin, dementia and types along with the history of how it was discovered. along with nvq 2 and care certificate that is done in our own time but not a choice. we all had to do it with no exceptions but were still only paid minimum wage even after all the courses i did. i did escorts to medical appts as well so needed to make sure i was up to date.
caring is a vocation as its not for the money. the owner insisted on training otherwise, you didnt get a job. it didnt help that nurses and medics didnt rate carers either.
this was precovid. i left 4 years ago after partial knee replacement after i injured my knee at work. this is my experience and no one elses. what they do in other areas, i dont know.
