NSPCC Whistleblowing Helpline
The NSPCC has launched a government funded Whistleblowing Advice Line. This will take calls from professionals from any sector who are worried about the way their, or another, organisation is dealing with child protection issues. Employees who don't feel able to escalate these issues internally can contact the service, as well as those who have been unsuccessful in doing so. It can be reached for free on 0800 028 0285 and can be contacted anonymously.
