Flex Effect — Designing Flexible Work Across Two Cultures

A four-round, intermediate HR strategy simulation set inside Linnea Industrial Software (LIS), a Barcelona-headquartered B2B software and engineering-services company of 1,450 people with a second business unit in Munich (€198M revenue, 13% margin). The two units have opposite work cultures and opposite problems: Barcelona (820 staff, younger, collaborative, office-attached) has a 19% voluntary-turnover retention crisis where 38% are 'actively considering leaving' and each regretted exit costs ~€62,000; Munich (630 staff, older, autonomy-oriented, client-site) has only 9% turnover but an engagement crisis at 61% versus a 74% target. After a competitor's four-day-friendly model triggers a talent walkout, the CEO gives the HR Director one quarter and a single fixed €1,200,000 budget — about 60% of what the two units' first-choice policies would jointly cost (~€1.95M) — to design a flexible-work policy across both units that cuts turnover and lifts engagement without breaking the budget. Playing the HR Director, you (1) diagnose why the same policy lands differently across cultures, distinguishing flexibility that reduces work-family CONFLICT from flexibility that creates work-family ENRICHMENT (Masuda's cross-cultural evidence); (2) choose a policy per unit — flextime, a compressed four-day week, or structured hybrid — set eligibility rules with a fairness principle for the ~40% of client-site and 24/7 roles that cannot flex, and allocate the €1.2M across both units under the cap; (3) handle a mid-rollout shock — Munich managers can't lead flexible client-site teams, a 24/7-support fairness grievance, and a customer losing Friday coverage — by investing in manager capability, defusing the backlash procedurally, and protecting service levels; and (4) commit to a leading-indicator KPI dashboard (turnover intention, satisfaction, work-family conflict, cost) and defend the case to the CEO to avert a uniform return-to-office mandate. The math rewards context-sensitive, enrichment-aware, procedurally fair design within budget and punishes the five classic errors — one-size-fits-all rollout, choosing the four-day week on appeal while ignoring coverage, treating flexibility only as conflict-reduction, overspending past the shared budget, and writing eligibility rules with no fairness principle. Final KPIs track Barcelona Retention, Munich Engagement, Eligibility Fairness, and Budget used against the €1.2M cap.
