Charities can work with businesses in several ways: commissioned work directed by the charity, partnerships through joint ventures, and direct support through fundraising, volunteering, sponsorship, or gifts-in-kind. When partnering with businesses, charities need to ensure the partnership aligns with their mission, safeguards their assets like reputation and brand, and considers potential positive and negative impacts. Trustees are responsible for advancing the charity's purposes and ensuring resources are used effectively. Charities must also make sure partnerships are compatible with their values around issues like wages, environment, and employee welfare.
