Exogenous Moments of Change at Work: How Short- and Long-Term Disruptions Reshape Environmental Habits and Behaviour

Sudden disruptions can destabilize everyday routines and open the door to pro-environmental behavioral change. This paper examines whether exogenous Moments of Change (MoC) with different temporal profiles—an acute nationwide power outage in Spain and the prolonged COVID-19 disruption—reshape employees’ workplace pro-environmental behavior (PEB) by weakening the relationship between habits and PEB. Study 1 surveyed 226 Spanish office workers 38 days after a brief blackout, while Study 2 followed 135 employees in Spain and the Netherlands longitudinally across the COVID-19 period. We found that, while reported PEB increased after both disruptions, the short-term blackout was insufficient to weaken the relationship between habits and behavior significantly, or to strengthen individual and organizational drivers of behavior. In contrast, the more prolonged COVID-19 disruption significantly weakened the influence of habits on PEB and strengthened the relationship between perceived corporate environmental responsibility and behavior. These findings suggest that the duration of a disruption is a critical factor. Specifically, brief shocks may elicit specific new behaviors; only prolonged disruptions appear sufficient to break established habits and enhance the influence of organizational factors on employees’ pro-environmental actions.
