A Complaint Between Two Employees Decision Tree

Why this matters

One tech comes to you about another. How you handle the first five minutes decides whether this stays a small workplace friction or becomes the thing that splits your crew and lands you a legal problem. Mishandle it - take a side, brush it off, or gossip about it later - and you teach the whole shop that coming to you is a mistake. Some complaints are a personality scrap you can mediate in a hallway. Some are harassment, threats, or safety issues that you are legally obligated to act on, fast. The tree below is about sorting which is which before you respond, because the response is wildly different.

Safety first: is anyone in danger right now?

Before anything else, check for immediate harm. This jumps the queue ahead of all fact-finding.

• If the complaint involves a threat, violence, or a weapon, separate the people now, do not leave them alone together, and treat it as a safety event - not a disagreement to mediate. Get the threatened person to safety and involve the right help.
• If it involves a safety violation that is live - someone working unsafe, impaired on a jobsite, bypassing a lockout - stop the unsafe work first, then deal with the interpersonal part.

Diagnosis of who-said-what waits. Removing the danger does not.

Triage: what kind of complaint is this?

Once nobody is in immediate danger, sort the complaint into a lane, because the lanes have different rules.

• Protected-category or harassment (about race, sex, religion, age, disability, or similar; unwanted sexual conduct; a hostile pattern): this is not casual mediation. It triggers a duty to investigate and act. Go to Branch A.
• A real workplace conduct problem (theft, bullying, sabotage, a serious safety breach): formal handling, documented. Go to Branch A.
• An interpersonal or work-style clash (they bicker, one is messy, they stepped on each other's job): mediation. Go to Branch B.

When you cannot tell, treat it as the more serious lane until you know better. It is far easier to step down than to explain why you treated a harassment report like a spat.

Branch A: serious - this is formal

For harassment, discrimination, or serious conduct, your job is to be a fair, documented process, not a buddy.

1. Listen fully and take it seriously, even if you doubt it. Do not promise an outcome and do not promise total secrecy - you can promise discretion and that you will only share on a need-to-know basis.
2. Write down what was reported, in the employee's own words, with the date. Documentation protects everyone, including the accused.
3. Do not retaliate and do not let anyone else retaliate against the person who came forward. This is the part that turns a complaint into a lawsuit when handled wrong.
4. Investigate evenhandedly. Talk to both people and any witnesses separately. Hear the accused out; do not convict on one account.
5. Get help if it is over your head. A serious complaint is a moment to consult an employment professional, not to wing it.
6. Act on what you find, consistently with how you have handled similar things before.

The rule for this branch: fair process, documented, no retaliation, decided on facts.

Branch B: interpersonal - mediate it

For a normal clash between two people who just are not getting along, you can usually fix it directly.

1. Hear each side separately first. You want the real story before you put them in a room, and people speak honestly one-on-one.
2. Look for the actual issue under the complaint. "He is lazy" usually means "I am carrying more than my share and nobody noticed." "She is bossy" often means "I do not know who is in charge on this job." The surface complaint is rarely the root.
3. Decide if it even needs a joint conversation. Some clashes resolve with a structure fix - clearer roles, different pairings - and never need a face-to-face. Do not force a kumbaya meeting that nobody wants.
4. If you do bring them together, set the rule: you are not here to relitigate every grievance, you are here to agree how to work together going forward. Keep it on behavior and the work, not character.
5. Land on something concrete. "From now on, whoever opens the job runs the job" beats "you two need to communicate better." Vague resolutions un-resolve by next week.

The rule for this branch: get under the surface complaint, fix the structure where you can, and land on a specific agreement.

Stay neutral, whichever branch

Across both lanes, a few errors do more damage than the original complaint.

• Do not take a side before you know the facts, even if one of them is your favorite. Picking early is how you lose the other person and your credibility.
• Do not gossip about it, not with other crew, not as a story later. The fastest way to guarantee nobody brings you the next problem is to be the person who repeats the last one.
• Do not let it vanish. "I will keep an eye on it" with no action tells both people you did nothing. Even a small visible step beats silence.

Recap: the order to work it

1. Danger check - threats, violence, live safety. Separate and protect first.
2. Triage the lane - serious/protected versus interpersonal. Default up when unsure.
3. Serious: document, do not retaliate, investigate evenly, get help, act consistently.
4. Interpersonal: hear each side, find the root, fix structure, land a concrete agreement.
5. Stay neutral and visibly do something, whichever lane it was.

The judgment to bank: your first reaction is the lesson the whole crew learns about whether you can be trusted with a problem. Slow down, sort the lane, and handle it like it matters - because it does.
