Because we are doing it already and have seen that it works. I have had two volunteers in my office that have both now found employment on this basis.
There are many charities that already have the procedures in hand to train volunteers and give them the necessary skills to enhance their abilities to return to paid employment. The government needs to endorse such a programme. Sometimes just the work experience and doing courses like First Aid, POVA and Child Protection can elevate a person's confidence and abilities enough to give them a start back on the career path. This would help organisations like the Red Cross attract more volunteers and help the government get people off aid whilst serving the community and making the volunteer feel good about themselves through worthwhile work.
