In many companies, a familiar pattern emerges in December: projects need to be completed “quickly”, while at the same time the demand for harmony increases in the pre-Christmas period, which is supposed to be “contemplative” but rarely is. This combination ensures that stress, conflicts and communication problems become more visible than at any other time of the year. The month acts as a natural stress test – and therefore provides valuable information on how stable teams and structures actually are.
Communication under stress
The dynamics in communication are particularly noticeable. Under high pressure, perception narrows, decisions become more short-term and misunderstandings increase. This can be explained by neuroscience: the stress system switches the focus to immediate reaction, while the ability to classify and differentiate decreases. However, organizations often expect maximum performance in this phase – and thus create a field of tension that manifests itself in January as delays or consequential conflict costs.
The harmony reflex and its side effects
Many teams react to this with caution or avoidance: “Now, just before the end of the year, we won’t talk about it anymore.” But it is precisely this reticence that leads to unresolved issues being carried over into the coming months. January then begins not with fresh energy, but with overdue clarifications.
How do we avoid overloading?
Resilient teams rely on clear priorities, transparent stress indicators and communication that does not gloss over but provides orientation. This includes the question: what is still realistically achievable this year – and what needs a structured framework in the new year? Dealing with overload is just as important. Organizations that interpret exhaustion as an individual problem often overlook systemic causes such as a lack of resources, unclear responsibilities or contradictory goals.
And here it is worth taking a look at the classics of team dynamics: Bruce Tuckman’s phase model explains why “storming” is particularly visible in December – the phase in which roles and expectations are negotiated. Anyone who believes that harmony is the goal is mistaken: norming and performing come after storming. Managers who resolve conflicts now accelerate this transition. In addition, Lencioni’s dysfunctions: When teams avoid conflict, there is often a lack of trust – and this is the basis for everything else. Those who recognize this do not use December as a burden, but as a diagnostic window.
December as an opportunity to take stock
December in particular offers the opportunity to make these factors visible. The phase of highest tension reveals what is easily covered up in everyday life: How teams work together, how leadership reacts and whether communication channels are viable. Such a year-end analysis is not a mood dampener, but a prerequisite for a realistic and stable start to the new year.
Naming burdens, clarifying expectations and sorting out priorities will not create more work, but relief. And prevent the new year from beginning with the legacy of an unspoken December.
