In an internal document obtained by Recode, 45 employees say they were demoted, pushed out or placed on less desirable projects after they filed complaints with human resources. Employees told Recode that Google continues to conceal, rather than address, issues ranging from sexual harassment to security.

In a statement provided to Engadget, Google's VP of People Operations Eileen Naughton said:

"Reporting misconduct takes courage and we want to provide care and support to people who raise concerns. All instances of inappropriate conduct reported to us are investigated rigorously, and over the past year we have simplified how employees can raise concerns and provided more transparency into the investigations process at Google. We work to be extremely transparent about how we handle complaints and the action we take."

After the walkout last fall, Google did update its policies for handling sexual misconduct. The company ended forced arbitration and outlined how investigations would be handled. Employees said that was a good start but not enough. Months later, one walkout leader left the company over alleged retaliation. Shortly after, another followed. By April, employees organized a town hall to share their experiences of workplace retaliation.

Recode's findings are consistent with the reports that have come out over the last year. But a document with dozens of employees claiming they've faced retaliation makes the handful of high-profile situations from last year appear to be part of a much bigger issue.
