Humor at work: what it does to a team

The meeting has run past the hour and the deadline is coming apart. Sarah points out that whoever built this schedule was clearly counting twenty days to a month, and the table laughs. The tension drops a notch and people finally start talking about what can still be saved.

Two weeks later the same team sits in the same squeeze, and this time the joke comes from Dan. He says the slippage is down to Chris and his "creative approach to estimates". Silence. Chris smiles the way people smile when they have no other option, and the rest of the meeting goes on who sent what and when.

Both jokes were equally quick and both aimed at the same thing: nobody is going to make the date. They differed in one respect only, namely who the target was and whether that target could answer back. That single difference explains most of what humor does at work, and most of where it reliably breaks.

What humor actually does to a team

Treating a laugh as the softener of a working day has research behind it, only far more cautious research than the usual sales pitch suggests. A meta-analysis led by Jessica Mesmer-Magnus in 2012 went through dozens of studies on workplace humor and found a fairly consistent picture. Where people laugh together and laugh kindly, teams tend to be more cohesive, and people report less stress and a better relationship with whoever is in charge.

Two honest qualifications belong with that. The effect is modest, so humor is not a lever that lifts a broken team; it is closer to grease, noticeable in how easily the gears mesh. And it is a correlation, not evidence of direction: it may equally be true that teams who work well together laugh more, because they have more to laugh about.

More interesting still is what we laugh at in the first place. Robert Provine spent years recording ordinary conversation on the street and in offices, and in a book published in 2000 he reported that most laughter does not follow jokes. It follows entirely unremarkable lines like "I have to go" or "you're kidding". Laughter, on his data, is roughly thirty times more likely in company than alone, which makes it a social signal rather than a review of the punchline.

That has consequences for any meeting. When eight people laugh at your remark, it is not necessarily a verdict on the remark; it is information that the table is on your side. Silence after a good line need not mean the line was weak, only that something is hanging in the room. And people laugh more readily at whoever sits higher in the structure, so the best laughs-per-joke ratio usually belongs to the boss.

When did you last laugh at work at something that was not funny? Most of us do it close to weekly and it does not feel like pretending, because it is not pretending. It is a way of saying "we're fine" in a place where the sentence "we're fine" would sound strange.

There is a warning in that against an easy conclusion. Plenty of laughter in a team is not by itself proof that people are comfortable in it. There is laughter at a compulsory away day too, only that laughter pays a tax to the situation. The difference is easier to hear in who starts the joking: where a team has settled, the quieter people join in too, not just the same two voices.

Four registers around one table

The psychologist Rod Martin described humor in 2003 as a combination of two independent axes. The tone can be warm or cutting, and the aim can be at other people or at yourself. Four positions come out of that, and nobody is only one of them. Most people have two stronger ones, and at work they run a narrower register than they do at home.

The axes are independent of each other, so you will regularly meet someone who bonds warmly in the meeting and spares nobody at the coffee machine. The whole quartet and its usual combinations are laid out in more detail in the overview of humor styles.

Humor from above: self-deprecation yes, sarcasm with care

A manager's joke does not weigh the same as a colleague's. It weighs more, because on top of its content it carries information about what is permitted here and who is currently in trouble. There is no way around that amplification; there is only a way to count on it.

What works best from above is humor aimed at yourself. When Sarah, as the team lead, opens a meeting by admitting that she did not understand her own slide from yesterday, she does two things at once. She shrinks the power distance and shows that an admitted mistake costs nobody their head here. The team takes more from that than from a two-hour workshop on open culture.

There is one condition attached, and it is the one that gets forgotten. Self-deprecation from above works as long as nobody doubts your competence, because then it reads as confidence. A manager who started last week and immediately runs himself down risks being taken literally, with the audience filling in the rest on its own.

Sarcasm from above is a different case. Between equals it is a game in which both sides return the serve. As soon as hierarchy holds one side in place, the serve does not come back: the person lower down laughs because laughing is the cheapest available response, and leaves with the sense of having been told off in front of witnesses. The manager, meanwhile, leaves with the sense of having lightened the mood.

The interesting part is that the barbed register is not stupid in itself. Experiments published in 2015 by Li Huang, Francesca Gino and Adam Galinsky showed that a sarcastic exchange raised creativity on both sides, in the author and in the recipient. The condition, though, was mutual trust. Without it only the unpleasant half of the exchange survives, and that is exactly the situation a boss walks into easily, because trust is not something to assume, however clearly you feel it yourself.

Where the ribbing stops

Sharp humor is the thing teams argue about most often and handle worst, because it turns quickly into a dispute about intentions. "It was only a joke" against "I didn't find it funny". Nobody can win that argument and it is beside the point, because the difference is not made by intent but by where the target stands.

Dacher Keltner and his colleagues described teasing in 2001 as a social game with rules. Between people who are close it works as a sign of affection: it goes both ways, it moves the target around, and it carries clear markers saying "this is play", meaning tone, a smile, obvious exaggeration. Without trust the same sentence is left with its bare content, and the bare content stings.

At work there are a few things worth watching, and they check out more easily than other people's minds:

• Does it come back? Where both sides take aim, it is a game. Where the arrows keep flying one way, it is something else.
• Does it repeat? One sharper remark is a remark; the same remark for the thirtieth time is a role somebody has been assigned without asking for it.
• A target with no way to leave the game is not playing one. A newcomer, or somebody two levels down, cannot show that it bothers them without drawing even more attention.
• The audience matters too. A joke at the expense of an absent colleague does not bring the team closer; it just redistributes for a while who is currently outside.

Most of the time this is not ill will but momentum. Somebody picks up a nickname in their first week, it catches on, and a year later it is a role nobody re-examines, because the person has meanwhile learned to fit it. Whoever handed the role out rarely notices. Whoever wears it rarely says anything, because in their own eyes speaking up would confirm that they cannot take a joke.

None of this is an argument for cautious silence. A team in which nobody dares say anything is not healthier, only quieter, and a sharp remark between people who trust each other is among the fastest ways to put an uncomfortable truth on the table. It is a question of dose and direction, and that line is thin enough to deserve its own piece on where teasing ends and mockery begins.

Interviews and clients: read the room first

In an interview, humor holds an odd position. It is one of the few signals available for showing that you are calm, and at the same time a situation in which you have less information about the room than anyone else in it. An uncomfortable combination.

Humor aimed at the situation is the safe bet: that you got lost in the building, that this is your fourth interview of the week, that the coffee here is stronger than most. Running yourself down is the risky one, even if you use it as insurance everywhere else. It works only where the audience already knows what you can do, because only then does it sound like confidence. In an interview nobody knows, and an admitted weakness is read literally, which is precisely what the hour is for.

A joke at a previous employer's expense never lands, not even when it is true. The person across the table automatically works out how you will one day talk about them, and that thought does not go away again.

Something similar applies with clients, only over a longer stretch. The sensible move is to follow their humor, not to deploy your own. When a client lightens up, lighten up too; when they do not, hold the businesslike tone rather than manufacture a mood, because forced fun reads as nerves. A joke carries information about how seriously you take the situation, and somebody paying for your work reads it closely.

One rule is worth holding to firmly: sarcasm does not survive writing. An email has no tone, no timing and no face, so a barb that would pass at the table as exaggeration arrives as a reproach. Dan found this out when he wrote to a client that "your brief is beautifully open to every possible reading". He meant it as a sigh about himself and about how many times they had already redone the thing. The client read it as an accusation, and two further calls went on something that had never existed.

Video calls have a trap of their own. A joke depends on timing and on seeing how the others react, yet in a call with eight people half the cameras are off, the audio arrives a beat late and nobody knows whether to laugh out loud or just nod. A remark that would pass in a room drops into nothing, and its author comes away unappreciated. At a distance it pays to joke half a degree gentler than at the table, and to keep the sharper versions for the next time you are all in one place.

How to find your register at work

Most people run a different humor at work than at home, and know it considerably less well. At home a long acquaintance corrects you, because they can afford to. At work, feedback on a joke almost never comes back, since nobody wants to give it: a colleague who does not enjoy your remarks simply says nothing and shifts their chair a little further away.

A fortnight is enough for a decent estimate. After every meeting or call, write down one sentence: what you said that was meant to be funny, who the target was (the situation, yourself, a specific person, nobody) and who laughed. Nothing more, no judgment. After two weeks a register you did not know about emerges, and for many people so does one name that shows up in the target column more often than the rest.

A faster starting point is the humor styles test. It asks about ordinary situations, and its result is best treated as a hypothesis to check against your own meetings rather than as a box. A humor register is a habit that can be tuned, not a verdict.

And one more thing you can manage as early as tomorrow. After the next meeting, do not replay what you said; recall who was looking down at the table at that moment. That look is a more accurate instrument than any questionnaire, and it costs you nothing but a glance around the room before everyone stands up.
