Google employees wrote a letter to their boss, CEO Sundar Pichai, urging that the tech giant to not be involved in creating technology that will potentially be used for warfare.
"We believe that Google should not be in the business of war," reads the letter, which was obtained by The New York Times and published Wednesday.
The letter, which is currently being circulated on an internal communication server among Google employees and has been for "several weeks," has collected 3,100 signatures so far, according to the Times.
Employees are upset about a partnership between Google and the United States Department of Defense called Project Maven. The conflict was first reported by Gizmodo in March.
