Apple is launching an "matching gift" program for charitable donations, CEO Tim Cook has announced through an internal memo. Beginning on September 15th, Apple workers who donate to a non-profit 501(c)(3) charity can have their funds matched dollar-for-dollar. The limit is $10,000 annually however, and Apple is also initially restricting the offer to full-time US Apple workers, expanding to other regions "over time," according to Cook. The decision excludes much of Apple's retail staff, which is frequently hired on a part-time basis.
