A project timeline slips, or a client launch goes slightly sideways. Before anyone even looks at the root cause, the Slack channel turns into a firing squad.
Sales says Operations can't execute. Operations says Sales overpromised. Marketing blames everyone. Everyone is pointing fingers, and the actual problem sits there, completely unfixed.
You read the thread, wondering how a group of highly paid, smart adults turned into rival middle-school factions overnight.
You're not imagining it. And it's not just "bad culture."
What just happened has less to do with your coworkers' character and everything to do with something called Social Identity Theory (SIT).
The core concept behind SIT is that we don't just see ourselves as individuals, we define ourselves by the groups we belong to: our team, our department, our profession.
And once we identify with a group, our brain starts doing something subtle but important: it favors the in-group and distances from the out-group.
Your colleagues aren't necessarily trying to sabotage the company. They're responding to a deeply embedded psychological drive to elevate their group's status and by extension, their own.
If they identify with "operations" and you with "sales," their brain is quietly working to maintain that distinction to achieve what social psychologists call 'positive distinctiveness.'
Pointing fingers reinforces the boundary. Admitting shared fault blurs the line.
The thing is, this same mechanism can work in our favor. When we feel strongly identified with our team - when we see our coworkers as part of "us" rather than "them" - reviews of workplace psychology show we're more engaged, experience greater emotional well-being, and are more likely to support each other.
This shared identity acts as a vital buffer against burnout. That's not nothing.
But it cuts both ways. The stronger the boundaries between groups, the more we'll see competition instead of collaboration.
So what do we do about it? Start by noticing when you're drawing lines. This week, pay attention to the language you use: "my team" vs. "their team," "we" vs. "they."
Those pronouns aren't neutral, they're markers of identity. When you catch yourself creating an us-versus-them dynamic, ask: what would change if I saw this person as part of the same group?
Second, make the in-group bigger. If you're leading a project, emphasize the shared identity: "We're all working toward the same goal here."
If you're navigating office politics, find the superordinate identity, the thing that makes you both part of the same "us."
It's not kumbaya, it's strategic.
The more someone sees you as in-group, the less they'll compete with you.
Third, use Monday to reset the frame. If last week felt like a turf war, this week can feel different.
Start a meeting by acknowledging someone's contribution from another department.
Invite collaboration instead of waiting for blame to be assigned. The more you reinforce a shared identity, the less energy gets wasted on invisible battles.
You don't need to fix your colleagues. You need to understand the game you're all playing and decide whether you want to keep playing it.
What identity lines have you noticed at work lately? Hit reply and let me know.
Did this resonate with you? Forward it on to someone who could use it too. These insights are better when shared.
Cheers,
