The HPS is totally reliant on volunteers. Without them, neither the national society nor the groups would exist.
Volunteers are people just like you, who lead otherwise busy lives and who have other interests but they are able to find an hour or more, each week, to help us. So, the next time that you see a vacancy advertised or you hear a call for volunteers, why not have a chat and find out what they are looking for. Talking it over does not mean that you are offering to do the job. Ask yourself how you could help. Can you change the job to suit what you can do? Can you do a part of the job or share with someone else? Remember that most people are more than happy to help their replacements to get to grips with the job.
