Announcing change: why a change of plan hits so hard

What you describe has little to do with the content of the change. It is about the mechanism behind it.

Predictive coding describes how the brain constantly maintains prediction models of its environment. The autistic brain weights the actual sensory input particularly strongly instead of buffering it with predictions. This means: every deviation from what was expected creates a so-called prediction error that has to be processed. And this processing effort is neurologically more expensive in autistic processing than in neurotypical processing, because the dampening through expectation is weaker. The comparison between "what I expected" and "what applies now" does not run in the background and is not automatically weighted as "not so important"; it lands in the system with full weight.

The decisive point: the scope of the change in content is irrelevant for this mechanism. What counts is the deviation from the model, not the severity of the consequence. Your employee had an internal model of what Monday, the week and the team structure look like. This model was discarded at short notice, unexpectedly and without lead time. The system now has to build a new model, and that costs capacity that is not available for work at the same time. The blockage you observed is this rebuilding.

On top of this comes autistic inertia. Once in a state, switching to another one uses a disproportionate amount of energy, because the circuits responsible for it are calibrated differently. Monday is structurally already a switch: from the weekend into the working week. The announcement on top forced another state change before the first one was complete. That does not simply add up, it multiplies the effort.

What this means for future situations: it is not the size of the change that decides how much it costs, but the lead time. The same change with one to two days of written advance notice before the conversation gives the prediction model time to adapt before the conversation takes place. The blockage on the day of the announcement is then much less likely.

The detailed questioning is not resistance and not a difficult attitude. It is the direct behavioural level of predictive coding. The autistic brain weights actual sensory and informational input more strongly than its own predictions. This means: when a change is announced, a comparison process starts immediately in the background. What stays? What goes? Who is responsible for what? Every open variable is a gap in the prediction model, and these gaps actively cost processing capacity until they are filled.

The mechanism behind this is intolerance of uncertainty. It is not a character trait but the experienced result of the predictive coding system: an environment with incomplete information forces the brain into a constant state of recalibration. That costs roughly as much as someone without glasses constantly trying to bring a text into focus. The energy is gone before the actual work even begins.

The questions "when exactly", "what stays the same", "who is responsible" are not a sign of scepticism about the change. They are the attempt to get the prediction model stable again as quickly as possible. Once this information is available, the process is complete and the energy is available for the actual task.

What the team experiences as resistance is the Double Empathy Problem. Autistic directness and informational need for detail meet neurotypical communication norms that read questions as a critical stance. Neither of the two styles is wrong. But without translation, a systematic misinterpretation arises in both directions: the team reads the questions as objections, while the employee is simply communicating her need for information.

In practice this means: the earlier and more detailed changes are announced, the shorter and rarer the questions become. Written change notices with a clear structure (what changes, what stays, from when, who is the contact person) answer the questions before they are asked and reduce the effort on both sides.
