Welcome to John J Zidziunas & Associates

Our Firm's mission is to achieve exceptional results for our clients through skilled, ethical advocacy and a commitment to excellence. Whether representing employers or employees in high-stakes, high-exposure litigation, we are prepared to take cases through trial and verdict when necessary. Regardless of the case's size or complexity, we fight relentlessly to protect our clients' rights through meticulous preparation, dedication, and strategic judgment.

One of our Firm's greatest strengths is our experience representing both employers and employees. Unlike firms that advocate exclusively for one side, our dual perspective provides valuable insight into how each side evaluates claims, assesses risk, develops litigation strategy, and approaches resolution. This breadth of experience enables us to anticipate opposing arguments, identify strengths and vulnerabilities early, and develop more effective litigation strategies tailored to our clients' objectives. By understanding the perspectives of both sides, we provide practical, objective counsel and sophisticated advocacy that serves our clients' interests at every stage of the litigation process.

John, Caroline, and the whole team took on my case with such ease and professionalism. They worked quickly to make sure I got what I needed in a timely matter, but most importantly what I deserved. My case opened in July and was basically complete within 5–6 months. I would highly recommend this firm.

FAQ — John J. Zidziunas & Associates

Answers to common questions

Frequently asked questions

Understanding your rights is the first step. Here are answers to the questions we hear most from employees considering a claim.

Every situation is different, but you may have a claim if you have experienced discrimination, harassment, retaliation, wrongful termination, wage theft, or a hostile work environment. The strongest cases usually involve documentation such as emails, texts, performance reviews, or witnesses. The best way to know is a free confidential consultation, where we review the facts and tell you honestly whether you have a viable claim.
We represent employees on a contingency fee basis, which means you pay nothing up front and no fee at all unless we recover money for you. Your initial consultation is always free. This structure lets you pursue your rights against an employer without financial risk, regardless of the size of the company you are up against.
Deadlines vary depending on the type of claim and the laws involved. Some federal discrimination claims must be filed with the EEOC within 180 or 300 days of the incident, while state law claims in New Jersey and New York often allow more time. Because these deadlines are strict and missing one can bar your claim entirely, it is important to speak with an attorney as soon as possible after an incident.
Document everything. Keep a record of dates, times, what was said or done, and who witnessed it. Save relevant emails, texts, and messages in a personal location, not just on a work device. Report the conduct through your employer's proper channels in writing if it is safe to do so, and avoid quitting before speaking with an attorney, as leaving too early can affect your rights. Then contact an employment lawyer to understand your options.
No. Retaliating against an employee for reporting discrimination, harassment, or illegal activity is against the law under both federal and state statutes, including New Jersey's Law Against Discrimination and the Conscientious Employee Protection Act. If you were demoted, fired, or otherwise punished after making a good-faith complaint, you may have a separate retaliation claim in addition to your original one.
It depends on the complexity of the case and whether it settles or goes to trial. Some matters resolve in a few months through negotiation, while others that proceed through litigation can take a year or more. We work to resolve cases as efficiently as possible while never settling for less than what our clients deserve, and we keep you informed at every stage.
We represent employees throughout New Jersey and across New York, including Manhattan, Brooklyn, Queens, the Bronx, Staten Island, Nassau County, and Suffolk County, with a Florida office serving the Miami area. Wherever you are located, we can discuss your situation during a free consultation.
