Future of Work · Long-form Report

Office attendance policies have hardened. The badge data has barely moved.

Employers across the United States and northern Europe have tightened requirements. Measured attendance shows compliance clustering into the same three days it always did.

Evidence: Reporting

Announced policy and measured behaviour have diverged in an unusually clean way. Mandates specify four days. Badge and occupancy data cluster around three, and the three are almost always the same three.

Why the middle of the week

Because attendance is a coordination good. Nobody comes in to sit alone. Once a critical mass settles on Tuesday to Thursday, the marginal value of attending Monday or Friday collapses, and no memo changes that arithmetic.

What employers have actually gained

The tightening has produced denser midweek offices, which has genuinely improved the informal contact that hybrid work erodes. It has also produced measurable attrition among senior individual contributors with the strongest outside options, which is the population the policy was least intended to affect.

What the better employers changed instead

Anchor days by team rather than by company. Specified in-person events with a purpose rather than an attendance count. And an honest acknowledgement that some roles genuinely do not benefit from colocation.

The measurement worth having

Occupancy by team on anchor days, not badge swipes company-wide. The first tells you whether collaboration happened. The second tells you whether people walked through a door.

"Tuesday to Thursday is not a policy outcome. It is what happens when people coordinate with each other rather than with the handbook."
