In one line: a sustainable-employability triage wall: nine team signals read into three root causes, then exactly two interventions — built to punish wellbeing-washing.

Why this kit exists

When absence rises, everyone proposes a fix and the visible one wins. The wall is engineered so the signals scream WORKLOAD DESIGN and MANAGEMENT PRACTICE (Monday-clustered absence, 23-hour meeting loads, a rota-swap black market) while the popular fixes — resilience training, the yoga programme — are designed traps. Reading precedes prescribing.

What the artifact does

Nine signal cards, each linked to one of three root causes with the wall's reading explained (including the Monday-curve logic and the yoga-poll-as-management-vacuum reading). Then two interventions from seven, with the wellbeing-washing traps given their own named debrief entries. Final advisory debrief tallies the cause distribution against the intervention choices.

The design decisions worth noticing

• The Monday curve as evidence — 44% of absence on Mondays is load-shape signature, and it rules out pure personal circumstance: lives do not know it is Monday
• The yoga programme scores zero — 78% popularity is why it tempts, not why it works; it may be offered, never counted
• The viral poll as signal — the decoy card itself carries a management reading: staff organizing their own fix while the organisation dithers is evidence

Honest limitations

Havenlogistiek Veldhoven and its signals are fictional composites of workplace employability patterns. Real employability advice follows the Arbo/wet-evidence path; the wall trains the root-cause-first instinct, not a diagnostic instrument.
