Alongside unspoken truths, there are spoken untruths. These undiscussables reflect discrepancies between what the team says it believes or finds important and how it behaves.
Teams often proclaim but fail to follow certain values, objectives, and practices that are supposed to guide and inspire them and create a sense of togetherness. The disconnect between what’s said and what’s done is visible to all, but no one points it out for fear of damaging team cohesion – even if that cohesion is based on a shared illusion. Go through this checklist to see whether this syndrome characterizes your team:
The chief concern in such teams is protecting the group, as opposed to protecting the individual, in the “think-but-dare-not-say” category of undiscussables.
Silence is not based on fear as much as on an unquestioned and distorted sense of loyalty to the team, its leader, or the organization. Drawing attention to the disconnect between intentions and actions would feel like letting down colleagues and killing team spirit.
This false positivity, which people express by simply mouthing accepted values, practices, and objectives, hides any concerns that the team might be incapable of making the necessary changes to the organization and that people might lose their jobs as a result. This protective impulse may appear innocent, but in the long run, it undermines learning and leads to disillusionment as people stop trusting one another’s words and commitments.
As team leader, you play a crucial role in initiating the necessary soul-searching process, stressing a collective responsibility to keep one another honest, listening to alternative viewpoints, and breaking down the unproductive and misconceived association of criticism with disloyalty.
