Most federal employees do not realize they are under investigation until it is too late.

One day you receive a vague email requesting a meeting.
Or a supervisor asks you to “explain something.”
Or HR says they are doing a “routine review.”

In federal service, nothing about an internal investigation is routine.

Whether your agency calls it a fact-finding inquiry, an Administrative Investigation Board (AIB), or a management inquiry, these processes are designed to gather evidence that can lead to:

  • Reprimands

  • Suspensions

  • Removals

  • Clearance issues

  • Suitability actions

  • Criminal referrals

  • Permanent reputation damage

This is why you must treat every internal inquiry as a serious legal event from the moment it starts.

The attorneys at the National Security Law Firm (NSLF) understand these investigations better than any other firm because we have been on the inside of them—at DHS, TSA, CBP, DOJ, military commands, and intelligence agencies. We know how agencies build these cases, where they cut corners, and how to dismantle the narrative they are constructing.

What Exactly Is an Internal Agency Investigation?

Federal agencies use several investigative tools to review alleged misconduct, performance concerns, harassment claims, integrity questions, or policy violations.

Common types include:

1. Fact-Finding Investigations

These are usually informal—but they are never harmless.
A supervisor or HR specialist gathers:

  • Witness statements

  • Emails

  • Records

  • Reports

  • Notes from informal interviews

Unlike a formal investigation, these often lack procedural protections, making them dangerous because the agency can shape the record without you ever knowing.

2. Administrative Investigation Boards (AIBs)

These are formal, structured investigations used across federal agencies and the military.
AIBs may involve:

  • A designated chairperson

  • A panel of investigators

  • Legal advisors

  • Comprehensive interviews

  • Document subpoenas

  • Written findings of fact

AIBs often lead to major adverse actions, suitability findings, and clearance issues.

3. Management Inquiries

Agencies often use this term when they want to investigate quickly without triggering formal procedural requirements. These inquiries are conducted by:

  • Supervisors

  • HR specialists

  • Non-neutral personnel

Despite their “informal” appearance, these inquiries can lead to:

  • Proposals to suspend or remove

  • Findings of misconduct

  • Placement on administrative leave

  • Referral to OIG or security offices

Any one of these investigations can end your career if mishandled.

Your Legal Rights During Internal Investigations

Federal employees—except some probationary employees—maintain robust due-process rights. Even in informal inquiries, you have the right to:

  • A representative (including a Federal Employment Lawyer)

  • Decline to answer improper questions

  • Avoid self-incriminating statements

  • Review certain evidence

  • Challenge inaccurate or incomplete reports

  • File grievances

  • Submit rebuttals

  • Pursue EEO or whistleblower retaliation protections

  • Appeal disciplinary actions through the Merit Systems Protection Board (MSPB)

  • File disclosures or retaliation complaints through the Office of Special Counsel (OSC)

Understanding these rights early—before you say anything—can save your job.

What Triggers Internal Agency Investigations

Internal investigations often arise from:

  • Coworker complaints

  • Supervisor disputes

  • Misunderstood emails

  • Performance friction

  • “Conduct unbecoming” allegations

  • Harassment complaints (even if false)

  • Timecard or attendance issues

  • Misuse of government property

  • Loss of trust or confidence

  • Whistleblowing (where retaliation is disguised as misconduct)

It is very common for agencies to weaponize “management inquiries” as a retaliation or pre-disciplinary tactic.

How Federal Investigators Collect Evidence Against You

Investigators typically gather:

  • Emails and Teams/Slack messages

  • Personnel records

  • Supervisor notes

  • Timekeeping records

  • Badge records

  • Access logs

  • Security footage

  • Statements from coworkers

  • Medical or EEO documents (inappropriately, sometimes)

Many employees mistakenly believe investigators will be fair or neutral.
They are not.

Internal agency investigations are designed to support the agency’s expected outcome, not to discover the truth.

The Most Common Mistakes Federal Employees Make During Investigations

Federal employees harm their cases when they:

  • Speak too freely in interviews

  • Provide unrequested explanations

  • Email coworkers about the investigation

  • Assume HR is on their side

  • Fail to secure representation

  • Give statements without reviewing documents

  • Forget that even “informal” meetings are evidence collection

  • Miss reporting retaliation early

  • Fail to build their own record

These mistakes are exactly what agencies rely upon.

Winning Strategy From a Federal Employment Lawyer

Here is exactly how NSLF handles internal agency investigations to protect careers and maximize outcomes.

1. We Immediately Identify the True Nature of the Investigation

Internal investigations often hide the real charge behind vague language like:

  • “Concerns about professionalism”

  • “Potential misuse of time”

  • “Inconsistencies in reporting”

We identify the actual allegation, which allows us to take control.

2. We Force the Agency to Follow Its Own Rules

Agencies frequently violate:

  • Notice requirements

  • Representation rights

  • Access to evidence

  • Deadlines

  • Union contract provisions

  • OPM or agency-wide policy requirements

Each violation becomes leverage.

3. We Craft a Controlled, Strategic Statement

You should never speak freely in an investigation.

We prepare:

  • Written responses

  • Limited statements

  • Corrective context

  • Legal objections

  • Requests for exculpatory evidence

This prevents accidental self-incrimination or misinterpretation.

4. We Build a Defense File That Beats the Agency’s Narrative

Our attorneys reconstruct the truth using:

  • Emails

  • Timelines

  • Supervisory inconsistencies

  • Coworker behavior patterns

  • Factual corrections

  • EEO or OSC retaliation theories

  • Evidence the agency overlooked or ignored

5. We Prepare for Potential Discipline Early

Internal investigations often lead to:

  • Reprimands

  • Suspensions

  • Demotions

  • Removals

We proactively prepare the Douglas factors mitigation arguments long before a proposal is issued, dramatically improving negotiation leverage.

6. We Maximize Career Value

Our goal isn’t just to avoid discipline.
It’s to protect your:

  • Promotions

  • Retirement

  • Reputation

  • Performance record

  • Future employment opportunities

  • Security clearance

  • Earning power

This is strategic, long-term career protection—not just damage control.

Frequently Asked Questions (FAQs)

Am I required to speak in a fact-finding interview?

Can investigators talk to coworkers behind my back?

Yes—and they almost always do.

Do I get copies of the evidence?

Not always upfront, but you have pathways to obtain evidence later.

Can internal investigations lead to discipline?

Very often. Even “informal” inquiries frequently result in formal actions.

What if my supervisor is biased?

Bias can invalidate findings. We use this as leverage.

Can I be placed on administrative leave during the investigation?

Yes. This is common in misconduct or conduct-unbecoming allegations.

Can probationary employees fight internal investigations?

Yes—especially in cases involving retaliation, discrimination, or whistleblowing.

Can NSLF stop the investigation?

We can often shape, redirect, or limit it—and frequently prevent discipline.

Can I request my own witnesses?

In formal AIBs, sometimes. In fact-finding inquiries, rarely—unless strategically demanded.

What if investigators misquote me?

We can challenge findings and submit corrective statements.

What happens after the investigation?

Findings are issued → management reviews → potential discipline → rights to respond or appeal.
