Workers who are organizing at Google say Monday's firing of four employees is an act of “illegal retaliation” from the company’s management intended to stamp out labor organizing.

Last week, roughly 200 Google employees protested the suspension of two workers—Rebecca Rivers and Laurence Berland—outside the company’s San Francisco offices for allegedly accessing and sharing internal documents, as well as tracking employee calendars, as previously reported by Motherboard. On Monday, Google fired both workers as well as two others who participated in the rally “for clear and repeated violations of... data security policies,” according to a memo posted by Google’s security and investigations team, first reported by Bloomberg News.
