Eloethan and Mishap I agree fully about the benefits of care homes being not for profit care. It's not a guarantee that nothing will go wrong, but when the emphasis is on caring well for their residents, rather than just making money for shareholders, the focus of their business is likely to be less mercenary.
The now defunct Southern Cross company bought up many homes in our area and had a dreadful record for repeated concerns about poor care or potential abuse, they were involved in "investigations" on several of their sites.
The council home care staff had been very well trained and supervised and had on going training.
I knew someone who was trying to be recruited by a private sector agency, they had no previous experience and where just being offered two days training.
This particular person while not likely to harm anyone, would not have had a proper clue or coped with the job and fortunately did not go for the post.
Agency recruiters are no doubt paid a bonus for getting an employee. so they might be more worried about getting a bonus than employing the right person.
