Is My Coworker Being Passive-Aggressive? How to Tell for Sure

You just read that email for the fourth time. Something is off. The words are polite — technically polite — but your stomach is doing that thing it does when someone smiles at you while twisting the knife. You are not imagining it. You are picking up on something real, and the fact that you cannot quite name it is exactly what makes it so disorienting.

Passive aggression in the workplace is not rare. A 2023 Preply survey found that 83% of Americans have received a passive-aggressive email at work. Two-thirds said it negatively affected their job performance. This is not a niche problem. It is one of the most common sources of workplace stress, and it thrives specifically because it is hard to prove.

The good news: there are structural patterns in passive-aggressive communication that are identifiable once you know what to look for. You do not need to be a psychologist. You just need to understand the mechanics of what is happening beneath the surface-level politeness.

Why Passive Aggression Is So Hard to Call Out

Passive aggression works because it gives the sender plausible deniability. If you confront them, they can say, "I was just being helpful" or "I didn't mean it that way." This is not a bug in their approach — it is the entire design. The message is constructed so that the hostility is felt but cannot be easily pointed to. You are left holding the emotional weight of an attack that, on paper, never happened.

This is why you keep rereading the email. Your nervous system detected something your conscious mind cannot yet articulate. That gap between what you feel and what you can prove is where passive aggression lives. It is a form of communication that weaponizes ambiguity.

The result is a particular kind of exhaustion. You spend mental energy trying to decode whether you are being reasonable or paranoid. You start second-guessing your own perception. And that self-doubt is not a side effect of passive aggression — it is the intended outcome. When you doubt yourself, you are less likely to push back.

The Five Structural Patterns of Passive-Aggressive Emails

Passive-aggressive messages are not random. They follow recognizable structural patterns. Once you can identify these patterns, the ambiguity dissolves and you can see exactly what is happening.

The first pattern is the performative courtesy. Phrases like "per my last email," "as previously discussed," or "just a friendly reminder" are not neutral. They are assertions of authority disguised as politeness. The word "just" is doing heavy lifting — it frames the sender as reasonable and you as someone who needs to be reminded. If you feel condescended to, it is because the structure of the sentence is designed to condescend while maintaining a surface of helpfulness.

The second pattern is strategic CC escalation. When someone copies your manager on a routine question, they are not being thorough. They are creating a witness to your response time, your tone, or your competence. The CC is a power move dressed up as process. If the same question could have been asked in a direct message and they chose to include your boss, that choice is the message.

The third pattern is the loaded question. "Did you get a chance to look at this?" is not a question about your schedule. It is an implication that you have been neglecting something. The passive-aggressive version of a deadline reminder never states the deadline — it implies you already missed it. The ambiguity is the point. If you respond defensively, you look guilty. If you respond casually, you look careless. There is no clean exit.

The fourth pattern is the compliment that diminishes. "Great job on the presentation — I know public speaking is hard for you" reframes your success as an exception to your general inadequacy. The compliment is the vehicle for the insult. If someone's praise consistently makes you feel worse about yourself, the structure of their praise is the reason.

The fifth pattern is selective silence. A coworker who responds to everyone else's messages in minutes but takes two days to respond to yours is communicating something. Silence is not neutral in a context where responsiveness is the norm. The pattern is not any single instance — it is the differential. When the delay is specifically directed at you, consistently, the message is being sent through what is withheld rather than what is said.

The Question That Actually Matters

Here is the thing most advice about passive aggression gets wrong: they tell you to focus on the other person's intent. "Maybe they didn't mean it that way." "Give them the benefit of the doubt." This advice sounds mature, but it actually makes the problem worse. It redirects your attention away from what you can observe and toward something you can never verify.

Intent is unknowable. Structure is observable. You will never know with certainty whether your coworker meant to undermine you. But you can look at the structure of their communication and ask: does this message create ambiguity where clarity was available? Does it position me as deficient while maintaining plausible deniability? Does the pattern repeat?

If the answer to those questions is yes, the intent is irrelevant. The structure of the communication is doing damage whether or not the person is consciously choosing it. Some people are passive-aggressive strategically. Others do it reflexively, without awareness. The effect on you is identical in both cases.

The question that matters is not "did they mean it?" The question is: "Is the structure of this communication consistently putting me in a position where I cannot respond without looking unreasonable?" If yes, you are dealing with passive aggression. Your perception is accurate. Trust it.

What to Do When You Are Sure

Once you have identified the pattern, the worst thing you can do is mirror it. Responding to passive aggression with passive aggression creates an escalation spiral where nobody ever says what they actually mean and everyone gets more entrenched. The second-worst thing you can do is ignore it indefinitely, because unaddressed patterns get more aggressive over time, not less.

The most effective response is direct, calm, and specific. Name the behavior without diagnosing the person. "When I receive an email that copies my manager on a routine question, it feels like an escalation rather than a process step. Can we handle these directly?" This approach works because it describes the structure, not the intent. You are not accusing anyone of anything. You are describing what happened and what you need to change.

If direct conversation is not safe — and in some workplace dynamics, it genuinely is not — documentation becomes your tool. Save the emails. Note the pattern. When you can show a consistent structural pattern across multiple interactions, you have something concrete to bring to HR or your manager. One ambiguous email is dismissible. Fifteen ambiguous emails with the same structural fingerprint are a pattern that demands attention.

There is also real value in getting an objective read on a specific message before you respond. When you are inside the emotional experience of receiving a passive-aggressive email, your ability to separate signal from noise degrades. Having someone — or something — map the structural patterns in the actual text can be the difference between a response you regret and a response that changes the dynamic. Tools like Misread.io can map these structural patterns automatically if you want an objective analysis of a specific message.

You Are Not Imagining It

If you found this article because you searched for whether your coworker is being passive-aggressive, I want to be direct with you: the fact that you are searching means your nervous system has already picked up the signal. You are not being oversensitive. You are not creating drama. You are responding to a communication structure that was designed — consciously or not — to make you doubt exactly this.

Passive aggression is effective precisely because it makes the target question their own perception. The moment you start wondering "am I reading too much into this?" is the moment the strategy is working. The search you just did is evidence of a healthy instinct, not a fragile one. You felt something, and instead of dismissing it, you investigated it.

Trust your read. Look at the structure. If the patterns are there, they are there. And now you know what to call them.
