The six staffers represent just under 10% of Warren's 70-person Nevada team. Three of them said they felt marginalized by the campaign, and that things only got worse after they took their concerns to human resources or their superiors.

"During the time I was employed with Nevada for Warren, there was definitely something wrong with the culture," said field organizer Megan Lewis, who joined the campaign in May and left in December. "I filed a complaint with HR, but the follow-up I received left me feeling as though I needed to make myself smaller or change who I was to fit into the office culture."

Another recently departed staffer, also a field organizer, granted anonymity because she feared reprisal, echoed that sentiment. "I felt like a problem — like I was there to literally bring color into the space but not the knowledge and voice that comes with it," she said in an interview.

She added: "We all were routinely silenced and not given a meaningful chance on the campaign. Complaints, comments, advice, and grievances were met with an earnest shake of the head and progressive buzzwords but not much else." A third former field organizer who was also granted anonymity said those descriptions matched her own experience. -Politico
