Brookfield Zoo Obstructs Animal Care — Teamsters Local 727 Files Injunction

Early this morning, Teamsters Local 727, through its outside counsel, Dowd, Bloch, Bennett, Cervone, Auerbach & Yokich, LLP, filed an emergency complaint in federal court seeking injunctive relief against the Chicago Zoological Society, doing business as Brookfield Zoo Chicago ('CZS' or 'Zoo'). Teamsters Local 727 represents approximately 200 Zoo employees, including animal care specialists. The Union and CZS have been engaged in negotiations for a successor collective bargaining agreement since February 2026 but have been unable to reach an agreement.

As a result of numerous unfair labor practice charges filed against CZS, hundreds of Teamsters employed by the Zoo went on strike at 5:00 a.m. on May 4. Despite the ongoing unfair labor practice strike, the Union continued to meet with Zoo management pursuant to provisions of the parties' collective bargaining agreement (CBA) that govern the provision of essential animal care during a work stoppage.

In its federal court filing, the Union alleges that CZS failed to meet its contractual obligations under these essential care provisions. Among the most serious allegations, the complaint asserts that CZS deactivated the electronic accounts and databases of animal care specialists — systems they rely on to access and record critical information such as veterinary appointments, prescription renewals, and animal health monitoring tools used to quickly identify and address illness.

The Union has asked the court to intervene and grant a temporary restraining order, preliminary injunction, and permanent injunction prohibiting further breach of these essential care provisions.

"Brookfield Zoo management should be ashamed of their petty behavior in locking employees out of vital electronic systems that are used to keep animals safe and properly cared for," said John Coli, Jr., Secretary-Treasurer of Teamsters Local 727. "Their outright refusal to honor their clear legal obligations has a direct and undeniable impact on these workers' federally protected right to strike and the welfare of animals. The Zoo had months to plan for this possibility and chose instead to do nothing. Neither the animals nor the bargaining unit should suffer because of CZS's lack of preparation for a work stoppage of its own making."

Teamsters Local 727 represents nearly 10,000 hardworking men and women throughout the Chicago area. Founded in 1903, the International Brotherhood of Teamsters represents 1.4 million hardworking men and women throughout the U.S., Canada and Puerto Rico.

Nothing in this statement should be read as the union's waiver of any legal argument, position or grievance(s), or as a waiver of any rights, arguments, or defenses under any contract, collective bargaining agreement, or applicable law. The union does not forfeit its right to make any and all supplemental arguments.

Zoo Management Must Drop Scare Tactics and Bargain in Good Faith for Fair Contract

As negotiations resumed on Friday, May 1, Teamsters Local 727 called on the Chicago Zoological Society (d/b/a Brookfield Zoo Chicago) management to do the right thing for its Teamsters members, the animals, and the institution itself by coming to the table with a fair and responsible contract proposal.

Instead of bargaining in good faith, Zoo management has relied on scare tactics designed to divide workers and mislead the public. Management has also claimed that Zoo employees are already fairly compensated, pointing to wage comparisons with states like Alabama and West Virginia. These comparisons ignore the reality of the Chicagoland area, where the cost of living is significantly higher and workers struggle to keep up with rising healthcare, housing, and everyday expenses.

"Zoo officials have suggested that fair wages and benefits for frontline workers would force higher admission prices," said Teamsters Local 727 Secretary-Treasurer John Coli, Jr. "What they neglect to mention is that they were already openly discussing a $3 increase in admissions to offset executive compensation, including costly buyouts for senior executives long before workers demanded fairness at the bargaining table."

"Our members at Brookfield Zoo are the reason it's a world class institution. Demanding the Zoo bargain in good faith, retain Union healthcare, have safe staffing levels, and be given fair raises isn't greed — refusing to give those things in exchange for inflated management salaries and buy-outs is…."

Zoo workers are the caregivers, keepers, and professionals who ensure animal welfare, visitor safety, and the Zoo's reputation for excellence. A fair contract is not just good for employees — it is essential to maintaining the integrity and future of Brookfield Zoo Chicago. Teamsters Local 727 urges Zoo management to stop the misinformation and propose a contract that reflects fairness, honesty, and shared values. The current collective bargaining agreement extension expired Friday, May 1 at 11:59 am.
