Rosen’s behavior included “shaking with anger,” “nhysically menac{ing] Montanus,” and “threaten[ing] her job,” id. § 112; openly fantasizing about committing violence against women, such as “smashfing] a brick into [a tax analyst’s] face to knock some sense into her,” id. § 116; and ignoring Montanus, sometimes for weeks at a time, id. 4 110. In or around June and October 2013, Rosen threatened Montanus’s job, stating that he would “write Montanus up,” unless she “change[d]” and became ““‘loyal’ to him, ‘or else.”” Id. 4112. Several times between October and December 2013, Montanus reported this incident and Rosen’s “incessant rage at her” to human resources. /d. 4113.

out of his office, slamming the door in her face.” Jd. Afterwards, Rosen “taunted her via email,” telling Montanus to “[w]ork it out with [her] boss,” seemingly in reference to Montanus’s earlier reports to human resources. id. Montanus “was initially afraid to report Rosen’s physical

attack,” but later reported the incident to Rosen’s supervisor and Columbia’s global head of equities.
