Do rude remarks undermine team performance?
In SHR — Swiss Human Resources' “Team Performance” programme, the quality of interactions deserves attention as a condition for getting work done, not simply as a matter of workplace atmosphere. The management question is specific: does allowing rude remarks to pass unchallenged compromise a team's ability to handle a demanding situation effectively?
What the literature establishes
Arieh Riskin, Amir Erez, Trevor A. Foulk, Kinneret Kugelman, Ayala Gover, Irit Shoris, Keren S. Riskin and Peter A. Bamberger (2015, Pediatrics) compared medical teams exposed to rude remarks during a simulation with teams that were not. In this randomised trial, exposed teams received lower ratings for their diagnostic and procedural performance. The finding establishes a causal effect within that setting, not an estimate directly applicable to every organisation.
A disruption that goes beyond feelings
Christine L. Porath and Amir Erez (2007, Academy of Management Journal) showed experimentally that exposure to rudeness could reduce task performance and helping behaviour. Their research concerns individuals, so it does not, by itself, demonstrate an effect on collective performance. It nevertheless sheds light on a mechanism relevant to teams: a demeaning interaction can disrupt work and reduce the help available between colleagues.
The premature conclusion
One might conclude that a high-performing team should avoid any uncomfortable statement. Yet these studies do not test professional rigour or factual corrections delivered without contempt. Asking someone to redo a non-compliant operation is not the same as belittling the person who performed it: eliminating the latter does not justify abandoning the former.

What the evidence does not allow us to promise
A medical simulation and experiments involving individuals cannot quantify the benefit of a courtesy rule in a factory. Nor do they establish that a one-off awareness session is enough to change interactions over the long term. In a bilingual environment, it is also necessary to distinguish awkward wording from personal disparagement, without assuming that language explains or excuses everything.
A practical check in Fribourg
In Fribourg, an exercise within the “Team Performance” programme could bring an agri-food team, a bilingual industrial team or a project team from the university sector together around a common rule: correct the observable fact and specify the required action, without judging the person. Before and after introducing this rule, over two periods of equal length, an observer would anonymously record corrective exchanges during work handovers, in both French and German. The primary measure would be the proportion of corrections containing both a specific fact and a required action, without personal disparagement; the proportion of handovers requiring subsequent clarification would provide a complementary operational indicator. This comparison would check how local practice evolves, without automatically attributing every performance change to the rule.
