When the #MeToo movement began taking down powerful men across every industry from TV news to Hollywood to publishing, many wondered why Wall Street was largely unaffected, considering the financial-services sector has never exactly been overly friendly toward women. The answer, of course, was the widespread practice of forced arbitration, in which many firms require any new employee to sign away their right to sue the company, ensuring that all claims are heard (and resolved) privately. Not only do such provisions give the company the upper hand, sparing executives from potential embarrassment and shame, but they keep fellow victims from finding out about each others’ allegations and banding together in class-action suits.

If that sounds like bullshit, it’s because it is! In February, congressional Democrats unveiled a bill that would ban mandatory arbitration and that same month, Google said it would give employees the right to sue the company. Meanwhile, the women of Wall Street have been fighting the arbitration fight themselves, telling abusive co-workers, no, you can’t act however you want with impunity. One of those women is Lee Stowell, a former Cantor Fitzgerald broker whose story Bloomberg recounts today:

Lee Stowell couldn’t find her Bernie Sanders mug. It was August 2016 at the Summit, N.J., outpost of Cantor Fitzgerald, the Wall Street brokerage. The tension in the office was becoming unbearable for Stowell—and not only because her colleagues couldn’t stand the rumpled-haired socialist on her mug. For a while, work had felt like a throwback to the early days of her career, when traders could spew invective with impunity, and women had to stomach it or find a way to hold their own.

Stowell scanned her desk, then took her hunt to the kitchen. She opened a cabinet, saw Sanders staring back at her, and reached for the mug. “I looked in,” she tells Bloomberg Businessweek. “There was feces in it.”

Yes, that’s right: Wall Street can be that disgusting. Amazingly, when Stowell complained about the colleague she suspected of defiling her mug—a salesman whose “conservative views clashed with Stowell’s liberal politics”—her boss reportedly told her to “be respectful” of the guy. It was just one of a number of indignities Stowell allegedly suffered over the years—including having her butt grabbed in 2015, and then being asked by a colleague, “would you rather he grabbed your boobs?” Later, Stowell was told by the company that she was part of the problem and “ordered her to take a course on appropriate workplace behavior.” Shortly thereafter, she was dismissed as part of a round of layoffs.

Finally, in April 2018, Stowell sued, but the case was held up over the question of her being allowed to take her claims to a jury, or if she was bound to an arbitration agreement. Lawyers for Cantor, which told Bloomberg it couldn’t comment on the case, argued that “Stowell’s recollections don’t matter because Cantor has her signature on a 2007 agreement, plus an updated electronic version she clicked on in 2014.” Stowell’s lawyer, though, argued that workers cannot be bound to checking a box on some boilerplate legal language, to say nothing of the fact men will continue to act however they please—that they will, for example, shit in someone’s mug—if they know their company will simply force women into arbitration. And, fortunately, a judge agreed!
