Service workers regularly face customers who question their competence, complain about waits they did not cause, or show visible annoyance when staff explain store policy. During the interaction, workers often respond by smiling and keeping a polite tone because training and job expectations encourage them to hide negative feelings.

Afterward, some workers use small acts of quiet retaliation to cope. They may be less attentive, take more time with a task, or slow their responses. Researchers call this behaviour "service sabotage," and they say these tactics can feel like regaining control in the moment.

However, the study found that such tactics can backfire. Workers replay the incident in their minds and this rumination can interfere with sleep. The findings appear in an academic journal, and the original post about the study appeared on Futurity. The research also notes that managers can take steps to better protect their teams, though it does not list specific measures.
