Stress is one of the key factors in determining how well your Duplicant is doing in the game Oxygen Not Included and at 100% they will be unresponsive to orders and proceed to vent Stress in their preferred way until it drops to 60%.

Each Duplicant has a different stress response. These responses trigger at 100% stress (stress is reduced after the 100% response). All responses stop the current errand in order to perform the response. These responses cannot be stopped by Red Alert or commanding the Duplicant to move.
