Team Building Series Lessons From The Ground Up Part 4- When One Person Shifts The Balance: The Hidden Cost Of A Team Out Of Sync

Have you ever had that one employee who drains 60 percent of your mental bandwidth before 10 a.m.?

I had one such employee who joined the new team I was building. Their unchecked attitude created havoc and tension inside a group that was still finding its rhythm. To say I was worried would be an understatement.

When you’re leading a new team, every person’s behavior carries extra weight. It’s like tuning an instrument, one off note, and suddenly the entire sound feels wrong. This employee’s negativity began seeping into side conversations, deadlines, even how others showed up to meetings. I could feel the energy shifting.

Instead of confronting them immediately, I spent a week observing.

What was actually happening beneath the surface?

Were they feeling insecure?

Misunderstood?

Testing boundaries?

Once I saw the pattern clearly, I realized this wasn’t defiance. It was uncertainty wrapped in defensiveness.

The fix wasn’t a lecture.

 It was a 1:1 conversation that started with curiosity, not accusation. I clarified expectations, named the impact of their behavior on the team, and asked how we could move forward differently.

Within a month, the tone of our meetings shifted. The tension eased. The rest of the team saw that accountability was real—but also fair. It took time but the investment paid off in the end.

Teams are like fruit bowls: they need care and careful inspection.

One neglected or unaddressed spot of mold can quietly undo all the work you’ve done to build something healthy. Your job as a leader isn’t to toss out the whole bowl. It’s to tend to it before the attitude spreads. One person’s imbalance ripples through everyone else, and as leaders, we have to restore alignment before the culture absorbs the strain.

It’s not about “fixing” people; it’s about protecting the conditions where everyone can perform at their best.

Who’s draining your mental bandwidth right now—and what would change if you tackled the pattern instead of the person?
