I am an Oxfam volunteer. I will still be an Oxfam volunteer next week because the 0.01% of people who are sexual predators shouldn't be allowed to destroy the good work of the 99.9%.
I don't believe there was a cover-up. The people involved were sacked or resigned. Legally, Oxfam could not pass on details of alleged wrongdoing to other agencies. There is NO evidence one way or the other about the age of the women involved - lots of speculation that they were underage but nobody knows. It was not taken to the police at the time because Haiti did not have a functioning police force. UK police could not get involved as it was non-UK citizens involved in something which happened outside the UK. Oxfam did NOT give them references - one French charity received a statement from Oxfam saying along the lines of "Mr X was employed by us from Y date to Z date" - that's a statement of fact, not a reference. The sacked people gave each other references, or gave personal references as ex-colleagues which is different. In many areas of the world when sexual assault is reported it's the woman who gets questioned and hauled into the police station, not the man.
Nobody within Oxfam is making excuses for what these men did as even if it wasn't rape, it was abuse of power. The charity has strong safeguarding and whistle blowing policies - there's a helpline poster in all stores with the regional HR manager's contact details for anyone to raise issues with, in confidience.
I didn't read Mark Goldring's interview but there does seem to be a sector of the media piling in to give all charities a good kicking. The bosses earn too much, none of the money goes to good causes, the shops are overpriced, the organisations are too political / not political enough, Oxfam is anti-Israeli, why are we funding developing countries anyway, charity begins and home, pigs with their snouts in the trough. All the same cliches which are always trotted out by people who don't give to charity and think that big charities shouldn't have any overheads whatsoever and should pay their CHief Exec minimum wage. And also failing to recognise that no organisation can EVER guarantee that there will be no sexual predators working for them as that's impossible. All they can do is to have robust policies to deal with it when it's reported.
Oxfam does hugely valuable work educating women and girls all over the world and improving basic conditions of sanitation and health. You are kidding yourselves if you think Oxfam is somehow intrinsically "worse" than any of the other big aid charities. I have found it a hugely supportive and tolerant place, accepting of people at all stages of their lives, people with disabilities and full of good, honest and downright decent people.
