In fact, a lot of these roles have a high degree of flexibility. Caring people is sometimes only a few hours at the beginning or end of the day or a few hours on a weekend to give a family respite, particularly if they have a child or a person in their family with a disability. So one of the reasons that this sector is not particularly well paid is because, actually, there is a high degree of flexibility and it's very, very difficult in some cases to deliver a career path that would lead to the typical progression in wages and salaries.
