> Thousands of Google employees and contractors around the globe—many of them women—briefly walked off the job Thursday to protest Google’s handling of sexual harassment claims and other workplace issues, and to demand more transparency around harassment incidents and pay levels at the company.
The aforelinked EEOC page [2] explicitly mentions that asserting your right to not be harassed is protected activity:
> communicating with a supervisor or manager about employment discrimination, including harassment
> Other acts to oppose discrimination are protected as long as the employee was acting on a reasonable belief that something in the workplace may violate EEO laws
