Workplace Discrimination Documentation Guide

What Is Workplace Discrimination?

Workplace discrimination occurs when an employer treats an employee or job applicant unfavorably because of a protected characteristic. Under federal law, protected characteristics include race, color, religion, sex, national origin, age (40+), disability, genetic information, and pregnancy. Many states extend these protections further — to sexual orientation, gender identity, marital status, and more.

Discrimination can occur in virtually any employment decision:

• Hiring, promotion, and advancement opportunities
• Pay, benefits, and job assignments
• Performance evaluations and disciplinary actions
• Termination, layoffs, and reductions in force
• Training and professional development opportunities

Discrimination is often subtle and rarely comes with an admission. Building a compelling case requires a detailed, well-organized record.

Types of Evidence That Matter

In discrimination cases, courts and investigators look for two types of evidence: direct and circumstantial.

Direct evidence is rare — statements or documents explicitly showing discriminatory intent, such as an email that says "we don't promote people like you." Most cases rely on circumstantial evidence, which builds an inference of discrimination through patterns.

Circumstantial evidence to document includes:

• Differential treatment compared to similarly situated employees of a different protected class
• Statements that reflect bias, even if framed as jokes or offhand comments
• Statistical patterns — e.g., employees of a certain group are never promoted
• Procedural irregularities — rules applied to you that weren't applied to others
• Changes in treatment after a protected characteristic became known
• A history of positive performance reviews followed by sudden criticism

What to Document: The Core Record

Every incident that could constitute discrimination should be documented in a contemporaneous log. For each incident, capture:

• Date and time — as specific as possible
• What happened — verbatim quotes, observable actions, not interpretations
• Who was involved — names, titles, departments
• Who witnessed it — names of everyone present
• Context — what led up to the incident, what happened immediately after
• Impact — how it affected your work, earnings, or wellbeing
• Comparators — note if you observed different treatment of colleagues outside your protected class in similar situations

Documents and Evidence to Collect

Written documentation is your strongest asset. Gather and securely store:

• Performance reviews — all of them, going back as far as possible
• Emails and messages — screenshot discriminatory communications or forward to personal email
• Job postings — if you were passed over for a role, save the original posting
• Organizational charts — to document promotion patterns within your team or company
• Compensation records — pay stubs, offer letters, any comparison data available
• Employee handbook and policies — to demonstrate when rules were applied inconsistently to you
• HR complaint records — any prior complaints you or others filed
• Meeting notes and agendas — when you were excluded or treated differently

Store everything on personal devices or in personal accounts. Company systems can be accessed — and purged — by your employer.

Comparator Evidence: Your Most Powerful Tool

One of the most effective ways to prove discrimination is to identify a "comparator" — a similarly situated employee outside your protected class who was treated better in the same or similar circumstances.

A strong comparator:

• Has the same or similar job title and responsibilities
• Reports to the same supervisor
• Had a similar performance history
• Was treated differently in an otherwise similar situation (discipline, promotion, termination)

Document these comparisons carefully without making accusations — focus on observable facts. "On the same project, [colleague's name] received a bonus; I did not, despite exceeding the same metrics" is the type of factual comparison that carries weight.

Building Your Timeline

A chronological timeline connects individual incidents into a coherent pattern. It shows when your protected status became relevant, when treatment changed, and whether there is a correlation. See our detailed guide: How to Build a Workplace Incident Timeline →

When and How to Escalate

1. Internal complaint to HR — file a written complaint. This creates a record and puts the company on notice. Keep a copy.
2. EEOC charge — if internal resolution fails, file with the Equal Employment Opportunity Commission. Time limits apply (180 or 300 days depending on your state).
3. State agency — many states have agencies with broader protections and longer filing deadlines.
4. Employment attorney — consult one before the EEOC deadline. Many work on contingency.
