Twenty-two aid organisations have said they are “truly sorry” for the sector’s failings in the wake of allegations of sexual misconduct by workers.
In a letter signed by chief executives, charities including Save the Children UK and Oxfam GB vowed to do more to protect those they were set up to help.
They also promised a series of “urgent and immediate” measures, including more resources for safeguarding.
“There can be no tolerance for the abuse of power,” the letter said.
“We have an absolute duty to our staff, our supporters and, above all, the people we seek to help to ensure we do everything in our power to prevent, detect and eradicate unacceptable behaviour.”
The charities admitted recent revelations had caused “widespread distress and disappointment” and said the sector needed to “fundamentally” change.
“Safeguarding is something that, as a sector, we have long taken very seriously and all our organisations have systems in place to prevent all forms of abuse and misconduct.
“However, we can never be complacent. We must do even more to protect the very people we were set up to help,” the letter said.
Abuse of power
Other measures announced include a review of the current referencing systems “so that people found to have abused their power or behaved inappropriately are not re-employed in the sector”.
Ex-Save the Children chief executive Justin Forsyth resigned from Unicef on Thursday after the BBC reported he had faced three complaints about his behaviour by Save the Children staff.
Unicef confirmed that the charity had not been aware of any of the complaints against Mr Forsyth at the time of his recruitment in 2016.
The aid organisations have also said they will work with the government “to ensure that we can overcome the legal and institutional barriers to rigorous background checks in the UK”.
The Charity Commission has said it had “extensive regulatory engagement” with Save the Children after allegations of misconduct and inappropriate behaviour were made against Brendan Cox – the husband of murdered MP Jo Cox – and Mr Forsyth between 2015 and 2016.
Mr Cox quit two charities he set up in memory of his wife last weekend after allegations of sexual assault were made public.
Mr Cox denied assaulting a woman in her 30s at Harvard University in 2015 – but admitted to “inappropriate” behaviour while working for Save the Children.
A petition calling for the resignation of international chairman Sir Alan Parker has been signed by some employees at Save the Children.
The petition claims Sir Alan, as chairman, was “ultimately accountable for both [Mr Cox and Mr Forsyth’s] cases” and also calls for “proactive, full public disclosure, to retain and regain public trust”.
In response to the petition, a Save the Children spokesperson said: “We are aware of the concerns expressed in the petition and believe it’s vital that everyone feels safe and secure when going about their work and interacting with colleagues.
“It’s precisely for that reason CEO Kevin Watkins has commissioned a thorough review of current practices and workplace culture.”
Meanwhile, Haiti has suspended Oxfam GB operations in the country as it investigates claims of sexual misconduct by staff in the aftermath of the 2010 earthquake.
Seven Oxfam members of staff left the charity in 2011 following the organisation’s own investigation into whether staff hired prostitutes while working overseas.
