When people are appointed as trustees of a charity, it is often because they either have knowledge of the charity's cause area or some other association with its work.
Although trustees must leave their personal interests aside in discussions relating to the work of the charity, every one of them will have contacts that have the potential to give a great deal to the cause.
Letting their personal contacts know when they become trustees of a charity can lead to discussions about the charity's aims and work, and bring interest in volunteering or making donations. It never fails to amaze me how often people are happy to offer information about useful contacts.
The contacts could even be from the companies that trustees work for. Many organisations are looking for causes to support, and if a trusted member of staff is involved at board level, this could be a short cut to offers that lead to successful fundraising.
It goes without saying that at no time should a trustee allow him or herself to reveal confidential details about the charity's work. But trustees should remember that general mentions of the charity's work can do no harm.
