Every year, around mid-November, something familiar happens in workplaces. Teams start to slow down. Energy drops. Focus feels harder to hold. People who were decisive a few weeks ago find themselves dragging tasks across the line.

It’s easy for leaders to misread this shift as disengagement or lack of motivation.
But the pattern is almost always the same and almost always human.

What you’re noticing is what psychologists call seasonal cognitive load. As the days get shorter, the brain naturally conserves energy. Add rising workloads, year-end pressure and limited daylight, and people begin to feel stretched before they say anything out loud.

This isn’t burnout.
It isn’t a performance concern.
It’s a natural, predictable dip that shows up in most teams every year.

The real question is how leaders respond to it.

Why it happens

1. Reduced daylight affects energy and focus

Exposure to daylight regulates mood, concentration and alertness. When that drops, so does mental stamina. People feel flatter without always understanding why.

2. Workloads expand as the year ends

Most teams enter November carrying more work, more pressure and fewer opportunities to recover. Even high performers feel the shift.

3. Expectations don’t always change with the season

When workload rises but clarity doesn’t, the cognitive cost climbs fast. People push harder with less energy to give.

All of this creates a quiet dip in performance – one that often goes unspoken until frustration builds.

How leaders can help their teams steady themselves

The good news is this time of year offers leaders a chance to make a meaningful difference. The changes that help most are small, practical and psychologically grounded.

Bring clarity to the noise

When cognitive load is high, people reach for certainty. Even a short conversation about priorities can take a surprising amount of pressure off.

Reset expectations, even briefly

Acknowledge the time of year. Adjust timelines where you can. Remind people what’s essential and what can wait.

Lighten the invisible load

Sometimes it isn’t workload causing the strain. It’s context-switching, unclear roles, or decision fatigue. A check-in can unearth this quickly.

Create moments to breathe

Five minutes at the start of a meeting. A genuine pause before the next push. A reminder that rest supports performance, it doesn’t compete with it.

Look for the quiet signs

A little less spark in meetings. Slower replies. More time to think. These aren’t red flags — they’re signals. Responding early prevents bigger dips in December.

Why this matters for leaders now

Great leadership is not about pushing through winter.
It’s about noticing what’s changing underneath the surface and responding with steadiness, not urgency.

Teams take their emotional cues from the people leading them. When leaders bring calm, clarity and care at this point in the year, they stabilise the team and restore energy where it’s fading.

A little leadership attention now can carry a team through the final stretch with more focus and less strain.

If you want support navigating these seasonal shifts

This is the point in the year when many teams reveal the dynamics that shape their performance – trust, clarity, motivation, pressure, and the way people respond to uncertainty.

Our psychologists help leaders understand these patterns and strengthen the conditions that keep teams steady, even when the season changes.
