Memo: Jack Dorsey plans a Block restructuring to remove business unit silos and group staff by function and warns that it may feel “disruptive or uncomfortable”

Context & Ripple Effects
Dorsey’s plan shifts Block’s operating model from product or business-unit ownership toward functional leadership, extending his more hands-on role during an earlier period of strain at the company. Dorsey’s return to running Square more directly provided the backdrop for this attempt to simplify coordination.
The memo also precedes later reports of another major Tidal workforce reduction and broader Block job cuts, making the reorganization an early marker of a longer effort to impose tighter operating discipline rather than an isolated org-chart change.
First-order effects
- Block employees and managers would be reassigned around functions rather than business units, changing reporting lines, decision rights, and day-to-day collaboration.
- Dorsey is signaling that short-term disruption is an accepted cost of reducing internal boundaries across Block’s businesses.
Second-order effects
- Shared functional teams can standardize priorities and resource allocation across products, but they also make each business’s needs compete more directly for central attention.
- The new structure creates clearer mechanisms for later cost actions: subsequent reports of jobs at risk during performance reviews suggest workforce efficiency became a continuing management focus.
Third-order effects
- If sustained, the shift would move Block toward a more centralized operating model in which functional efficiency carries greater weight than autonomy for individual business lines.
- For diversified fintech platforms, this is part of a broader test of whether organizational simplification can restore accountability without weakening product-specific execution.
The trend: Block’s reorganization is one data point in the post-growth push by multi-product tech companies to replace siloed expansion with centralized functional discipline.
