The people who care for my mum now, in a care home, and those who cared for her in her own home before she became too ill are saints. I would trust them with my life. They deal with truculent people every day. My mum has to be persuaded to eat 'just a bit more' at every meal now. Some of the residents in her home will ask for a cuppa, fall asleep, wake up and moan that it's cold and the carer will go off to get them another cup. No moaning, no whinging.
They clear up explosive poo accidents (and I mean everywhere, not just on the resident as the residents decide to use their hands to clear up...)
They get people back on their feet after falls - helping them walk and, in some cases, using wheelable stand up trolleys to get people around. They dress, undress, shower and shave residents. In my mum's home they do manicures for the women because it makes them feel nice. They arrange visits to stimulate the residents (who usually moan about being kept awake so they can't win). They deal with family, often having to break difficult news if their loved one is ill and has had the doctor in to see them. We've just had to put an 'end of life' plan in place for my mum with the help of her senior carer as she has been unwell on and off for a long time and antibiotics don't cut it anymore.
They have reams of paperwork every day and deal with GPs, social services, district nurses etc., Quite apart from the constant bell ringing for those who are too ill to sit in the main living room. Even then they make sure everyone who can get out of bed does so and those who can walk has a walk around every day. Over forty residents.
And you want the unemployed to do this? Some of whom may be shopworkers, teachers, builders - i.e. no background in the wok at all. Would you trust your kids to a teacher who had no experience? Or your new extension to just anyone off the street? So why would you trust your elderly relative to someone who has no experience and no aptitude.
Quite apart from the fact that the money has to come from somewhere. Why should anyone have a low wage just because, in the past, people from other countries have been prepared to accept that? If the jobs need filling, the money has to be found. Not forced labour from people who still need benefits to 'top up' for a bloody hard job that I wouldn't want to do.
And, of course, some of the unemployed are high wage earners who've been made redundant. Sometimes it can take them a while to get back into work. When my husband was out of work a couple of years ago, it took 3 months to find a job, another month of humming and ha-ing before they decided to call for interview (internal politics), three interviews (up to board level) which took another 4 -5 weeks. So in all it was 6 months out of work. At what point does he get told - leave that potential high paid job application and go and work for this care home in your utopia world? Do you wait 6 months, a year? Some roles take a lot of organising - relocating family, retraining etc. So who would be put forward for all these fictitious jobs OP?
