Under the standards, drawn up by Volunteering England as part of its ongoing inquiry into volunteer rights, the organisations have pledged to make one of their trustees responsible for monitoring complaints from volunteers and to give volunteers a hearing if they are unhappy with the way they have been treated.
The standards cover the responsibilities of charities towards their volunteers, the procedure for reconciliation with dissatisfied volunteers and the ways in which charities can promote best practice in volunteer management.
They also include ensuring volunteers' concerns are listened to, making sure all staff know how to deal with situations where things go wrong with volunteers and exploring local mediation services where necessary.
Sukhvinder Kaur-Stubbs, chair of Volunteering England, said: "This is an important step forward in improving the conditions for volunteers where, in some instances, they fall short of expectation.
"This approach will ensure that any steps taken are proportionate to need, respect the reciprocity of volunteering and promote parity of esteem between paid and volunteer staff."
The full list of charities signed up to the scheme:
- Cancer Research UK
- St John Ambulance
