Workplace Investigation or Employment Lawyer? How to Tell Which One You Need

A complaint pops up in your inbox. It involves someone senior, or it involves the person who normally handles complaints, and the “usual process” might start to feel like the wrong approach. The next question is who to call.

We put together this breakdown of what each option gives you, including the cases where a lawyer is clearly the right call.

When your own HR team can’t be the neutral party

Plenty of complaints should stay in-house. A policy violation with clear facts, a first-time attendance issue, a disagreement between two peers on the same team: HR can handle those, and pulling in an outsider would be overkill.

But the internal option doesn’t work as well in specific situations:

• The subject is a senior leader. Your HR person’s job security runs through the leadership team. Even when they’re fair, they’re being asked to investigate someone with influence over their career.
• The subject is in HR. When the department investigates itself, the process loses credibility no matter what the finding turns out to be.
• Everyone already knows everyone. For small companies, HR likely has a real relationship with the complainant, the respondent, and most of the witnesses. That’s a liability.
• Nobody in-house has done this before. Investigation is a skill. If your HR experience is recruiting, benefits, and day-to-day advising, a harassment complaint is not the right place to learn interviewing and documentation on the fly.
• There’s no time. These are time-sensitive. A complaint that sits for three weeks because no one has time creates its own exposure.

When to call an employment lawyer

Some complaints just aren’t fit for HR question and are a better fit for an employment lawyer:

• Something has already been filed. A lawsuit, a demand letter from an employee’s attorney, or a charge from the EEOC or your state commission. You’re defending a claim now, and that’s legal work.
• The conduct might be criminal. Assault, threats, theft, anything you could end up reporting to the police. Get advice before you interview anyone.
• A contract or union agreement is involved. An employment agreement or a collective bargaining agreement may spell out steps you’re required to follow, and missing one creates a second problem.
• You’re heading toward a separation with money attached. Severance and release agreements are legal documents, and they should be drafted like it.

The other reason employers call a lawyer is privilege.

Attorney-client privilege means your private conversations with your lawyer are protected. If the employee sues you, their attorney can’t make you hand those conversations over, and neither can a state agency looking into a charge.

The common assumption is that running an investigation through a lawyer wraps the whole thing in that protection, so the report and the notes never reach the employee’s attorney at all.

It can work that way. There’s also a catch that surprises a lot of employers.

Say you get sued a year later, and your defense is that you looked into it and handled it appropriately. You’ve now made the investigation part of your argument, and courts have generally held that you have to produce the investigation once you do.

So the protection holds right up until the moment you want to lean on it. If the plan is to point at the investigation as proof you did the right thing, assume the employee’s attorney gets to read all of it.

One more thing to consider. Employees frequently won’t speak freely to a lawyer they read as the company’s defense attorney. Witnesses hedge, or they leave things out, and you end up knowing less than you would have.

When a neutral third-party investigator is the right call

If what you need is a credible set of facts, a neutral investigator might be the right fit.

Someone with no stake in the outcome, no reporting line into the people involved, and no history with anyone involved does the interviews and writes up what they found. The report carries weight with employees, with your board, and later with a regulator or a court precisely because the person who wrote it wasn’t on anyone’s side.

This is usually the better fit when:

• The allegation involves an executive, an owner, or a board member.
• The allegation involves HR, or HR is closely tied to the people involved.
• The finding will need to be explained to a skeptical workforce.
• You need documented process and a defensible record more than litigation strategy.
• Your team has the will to do it right but not the experience or the hours.

And yes, sometimes you can use both a neutral investigator and an employment lawyer. A neutral investigator handles the fact-finding while your employment counsel advises you separately on exposure and on what to do with the findings.

How to decide, and what to ask before you hire either one

Ask yourself the following questions:

• Active claim, charge, litigation, or possible criminal conduct? Call your employment lawyer first.
• Need credible facts about what happened, especially involving leadership or HR? Bring in a neutral investigator.
• Routine, contained, and your team has done this before? Handle it internally and document it well.
• High stakes and legally complicated? Consider using both.

One rule matters regardless of who you hire: the investigator finds facts, and you decide what happens next.

When the same party investigates and then hands down discipline, employees read it as predetermined. Keeping those roles separate protects the credibility of both.

Need help evaluating? It’s worth asking any investigator or firm before you engage:

• How many investigations like this have you handled?
• What does your report include, and what does it leave to us?
• Will you make a finding, or only summarize what you heard?
• How do you handle it if a witness won’t talk?
• How fast can you start, and what’s the expected timeline?
• What does this cost, and how is it scoped?

Next steps
