Evidence Needed in Age Discrimination Cases

Your Word Helps, But You’ll Need More Than That

You know something’s wrong. You’ve worked hard, stayed loyal, and now, for no clear reason, you’re being left out of meetings, passed over for projects, or even pushed out of your role entirely. Maybe no one said anything explicitly about your age, but the tone has changed. Your instincts aren’t wrong, but your story alone won’t be enough to win a claim.

Age discrimination cases require proof. That proof can come in many forms, but courts, agencies, and employers will look for more than emotion or memory. They’ll want documentation, comparisons, and concrete examples.

At Horn Wright, LLP, our employment law attorneys help New Yorkers turn their experiences into persuasive legal claims. That means gathering real evidence, assembling timelines, and using the law to hold employers accountable.

Types of Documentation That Strengthen Your Claim

In New York, both the Age Discrimination in Employment Act (ADEA) and the New York State Human Rights Law (NYSHRL, Exec. Law § 296) prohibit discrimination against workers age 40 and over. But employers rarely admit to age bias openly. They’ll cite vague performance issues or claim “restructuring.” That’s why documents can be so powerful.

Start gathering whatever you can, including:

• Performance evaluations: If your reviews were consistently strong and then suddenly turned negative without clear justification, that pattern may show a shift in how your work was judged once you hit a certain age. Consistency in evaluations matters, and sharp unexplained changes can suggest bias.
• Work assignments: If you were taken off high-profile tasks or excluded from client work you handled for years, it’s worth noting. These changes are often framed as company decisions, but when they consistently sideline older employees, they raise legal red flags.
• Internal complaints: Emails or memos to HR that were ignored, dismissed, or resulted in retaliation are useful. Under ADEA § 623(d) and NYSHRL § 296(7), retaliation is separately unlawful, and documenting it can make your case stronger overall.

You don’t need everything at once. What matters most is collecting early, keeping detailed records, and noting patterns as they emerge.

Internal Emails, Policies, and Peer Comparisons

Some of the best evidence isn’t always obvious at first. Internal messages, corporate policies, and comparison to younger peers often expose the deeper picture. These sources may seem minor, but they help show intent, something both federal and state law consider when evaluating discrimination claims.

New York courts, in particular, recognize the value of circumstantial proof. NYSHRL § 297 allows employees to present patterns and context, not just direct insults or admissions, as valid evidence.

What you can look for includes:

• Internal communications: Search for emails or chat messages with language like “we need younger energy” or “time to refresh the team.” Even if these weren’t said to you directly, they can demonstrate a company mindset that prioritizes youth.
• Company policies and memos: Look at how promotions, layoffs, or transfers are discussed. Policies that favor certain age groups, even indirectly, may not meet the standards required under ADEA § 623(a).
• Comparisons across age groups: Make a list of coworkers in similar roles, noting their age, performance reviews, and any recent promotions or demotions. Patterns showing younger employees moving up while older ones are reassigned, demoted, or let go can be compelling.

Keep these records detailed, dated, and stored safely. Even one or two well-documented examples can back up months or years of subtle discrimination.

Testimony from Co-workers or Past Employees

The people you work with, or used to work with, can offer powerful support in an age discrimination claim. They may have witnessed comments or decisions you weren’t even aware of. In some cases, they’ve experienced the same bias themselves.

Under both ADEA and NYSHRL, testimony is considered a valid form of evidence. And you don’t need a large group to prove your case. One honest, detailed account can have a big impact.

You may want to ask:

• Current colleagues if they noticed any shift in how you were treated compared to others
• Former employees who left under similar circumstances and are willing to share what they saw
• Supervisors or HR personnel who no longer work at the company and might feel freer to speak

Always approach these conversations with care. People may be hesitant at first. Let them share only what they’re comfortable disclosing, and talk with an attorney about how to legally preserve and present their input.

In Vermont, More Emphasis Is Placed on Direct Evidence, While New York Accepts a Broader Range

Every state sets its own tone for how age discrimination cases are handled. In Vermont, courts tend to lean heavily on direct evidence, such as outright ageist remarks or emails that clearly link decisions to age. That can make proving your case more difficult, especially when employers use coded language or unofficial practices.

New York law, on the other hand, accepts a broader range of evidence, including:

• Pattern-based discrimination: Showing that older employees as a group were disadvantaged, even if you don’t have a single direct quote
• Comparative treatment: Demonstrating that you were treated differently from younger colleagues with the same job title or qualifications
• Implied bias: Using indirect language or behavioral patterns to build a case under NYSHRL § 296(1)

This approach gives older employees in New York a better chance to make their case, even when the discrimination is subtle or hidden behind company speak.

What to Do If You Suspect Documents Are Being Hidden

It’s unfortunately common for companies to delay, deny, or destroy documents that could help your case. If you’ve asked for personnel files or HR memos and received vague responses, or were told the documents don’t exist, that could be a red flag.

The best thing to do is act quickly but calmly. Avoid accusing your employer directly. Instead:

• Keep a written log of every document you request, including dates and who you asked
• Save any emails or responses where your employer claims files are “unavailable” or no longer exist
• Preserve copies of anything you legally accessed during your employment, such as emails or reviews, as long as you follow company policy when doing so

Under federal and state laws, intentionally destroying evidence can lead to penalties and strengthen your claim. But to make that argument, you’ll need to show your efforts to get the records, and the company’s failure to respond.

Legal Tools to Demand Records and Proof

Once you file a formal complaint, your legal options expand. Both the Equal Employment Opportunity Commission (EEOC) and the New York State Division of Human Rights (NYSDHR) offer procedures to help you get the records you need to support your claim.

Working with an attorney, you can use several legal tools:

• Discovery requests: These formal requests can be used once your case progresses, forcing the employer to hand over internal files, emails, salary records, and more. This step is key in both EEOC and NYSHRL litigation.
• Subpoenas: Courts or agencies can issue subpoenas requiring companies, or even third parties, to provide records or testimony. Subpoenas are especially helpful when key people have left the company or when documents are being withheld.
• Depositions: Your lawyer can question managers, HR personnel, or decision-makers under oath, revealing motivations or inconsistencies. Their testimony becomes part of the legal record and can support both discrimination and retaliation claims.

These tools are often what turn a suspicious pattern into a proven case. And in New York, they’re available at both the federal and state level to support your claim.
