Self-described Apple workers, former employees, and shareholders are calling on the company to halt donations to nonprofits linked to Israel’s war effort.

An open letter from Apple employees and shareholders demands the tech giant stop matching employee donations to organizations with ties to the Israeli military assault on the Gaza Strip and ongoing illegal settlement development in the West Bank.

The letter, building on a previous demand by Apple employees for a ceasefire in the conflict, calls on the company to “promptly investigate and cease matching donations to all organizations that further illegal settlements in occupied territories and support the IDF.”

As with many large corporations, Apple employees can make donations to a number of nonprofit organizations and receive matching contributions from their employer through a platform called Benevity.

Among the charitable organizations eligible for dollar-matching from Apple are Friends of the IDF, an organization that collects donations on behalf of soldiers in the Israeli military, as well as a number of groups that contribute to the settlement enterprise in the West Bank, including HaYovel, One Israel Fund, the Jewish National Fund, and IsraelGives.
