Most health care workers in the UK would work for the NHS, although there are private hospitals and care homes that also employ health workers. There are also care assistants that work in peoples homes. There are many different sectors within this part of the job industry and these can be split into different sections as well.
You may work as a dentist or dental nurse, doctor or nurse or in physiotherapy or other human health areas. You may have a hands on role or be more involved with paperwork, perhaps as a receptionist or administrator.
