A New Jersey woman is suing casino chain Caesars for fostering a male-dominated culture that looked the other way as she was retaliated against for complaining about a creepy incident with a superior, according to her lawsuit.

Jocelyn Agnellini Allison says her career at Caesars started to suffer after she complained in May 2017 about a direct superior who was seen “making out” with a subordinate after a work function.

The since-fired regional vice president of marketing reported the make-out session after two of her own reports complained that it had “made employees uncomfortable,” according to the Trenton federal lawsuit.

Days later, Agnellini Allison’s boss — regional president Kevin Ortzman — began telling people “there will be hell to pay” once he found out who ratted on him, the lawsuit said.

Agnellini Allison was then excluded from “executive team thank you e-mails” and even holiday gift giving, the lawsuit said. She was kept out of meetings, “treated in a hostile and dismissive manner” and “falsely” accused of abusing her position and administrative compensation privileges, the lawsuit said.

By February 2019 she was fired without explanation, she said.

The lawsuit knocks Caesars for “having an underrepresentation of female employees, particularly female employees in high-level positions,” and says another employee who complained about Ortman’s “unlawful sex based contact,” was fired at the same time as Agnellini Allison.

“Defendants’ upper management participated in, or were willfully indifferent to, the violations,” the suit said.

Agnellini Allison declined to comment through her lawyers. She is seeking unidentified damages from two Caesars’ corporate entities named as defendants.

Caesars, which also declined to comment, has until July 26 to respond to the complaint. Ortzman, who is not named as a defendant, did not return calls by presstime.
