When you are buying for an organisation that depends on donations and volunteer support, it is not hard to keep staff focused on making sure every penny counts. Oxfam GB (OGB) staff know that wasting £25 means a family in the Niger misses out on a goat and the chance to pull themselves out of poverty. They also know the effort that goes into fundraising that money.
Ensuring that the organisation that publishes humanitarian and ethical guidelines for protecting workers in global supply chains is itself beyond reproach is rather more difficult.
