The Combined Federal Campaign (CFC) is a workplace giving program that allows federal employees to donate to charities through payroll deductions. It aims to promote philanthropy in an efficient, cost-effective manner. Employees have a choice in which charities their donations support and can give as little as $1 per week. The CFC reviews charities annually to ensure donations are used appropriately. It has operated for over 45 years and provides a convenient way for federal workers to support causes they care about.
