Chicago, IL – 100 nurses and their allies gathered outside the Cook County Pension Fund in downtown Chicago on Augurst 27 demanding the fund sever ties with Palantir, a surveillance technology company. National Nurses United (NNU), the largest union of registered nurses in the U.S., organized the Chicago protest, as well as seven others across the country.

NNU’s campaign to “Purge Palantir” comes as many hospitals establish deeper ties with the company. Some hospitals use Palantir to automate nurse staffing, laying off local managers and worsening working conditions. Other hospitals share patient data with Palantir, which then uses that information so ICE can target and deport immigrant patients.
