Microsoft on Thursday fired two additional employees after firing two others a day prior, following a break-in at the office of its vice chair and company president, Brad Smith, earlier this week, as part of a protest of the technology company's purported links to Israel. "Two additional employees were terminated due to serious violations of established company policies and our code of conduct, including participating in recent on-site demonstrations that created significant safety concerns for our employees," a Microsoft spokesperson said in a statement to CBS News. The terminations came after a group of seven people broke into executive offices at Microsoft's global headquarters in Redmond, Washington, on Tuesday to hold a sit-in. No Azure for Apartheid, an advocacy group organized by Microsoft employees, said in an Instagrampostthat current and former workers from Microsoft, Google and Oracle were part of the group that occupied Smith's office. The protesters, who were arrested by police on Tuesday, were demanding that Microsoft cut ties with Israel after The Guardianreportedearlier this month that a unit of the Israeli military is using Microsoft's Azure cloud platform to surveil Palestinians in Gaza and the West Bank. "Two employees were terminated today following serious breaches of company policies and our code of conduct," a Microsoft spokesperson said in a statement to CBS News on Wednesday. "The first violated the Business Conduct Policy, participated in the unlawful break-in at the executive offices, and other demonstrations on campus, and was arrested by authorities on our premises on two occasions. The second was involved in the break-in at the executive offices and was subsequently arrested." A Microsoft spokesperson said in the statement Thursday that the company is "continuing to investigate the conduct on our campus and work with law enforcement to help ensure the safety of all our employees. We wish to emphasize, again, as we did in a statement yesterday, that such conduct is entirely unacceptable and stands in direct opposition to our company values and policies." In an Instagrampost, No Azure for Apartheid identified two of the employees as Anna Hattle and Riki Fameli. During a pressconferenceon Wednesday, Smith said Microsoft has launched a formal investigation into Israel's reported use of Azure. "We are committed to ensuring that our human rights principles and our contractual terms of service are upheld in the Middle East," he said. Protests against Microsoft over the Israeli military's use of the company's technology have been going on for months. Police last weekarrested18 people after a similar protest at the company's Redmond headquarters.
