More Mandates, Same Attendance: What the Data Actually Shows About RTO
VergeSense is the industry leader in providing enterprises with a true understanding of their occupancy and how their offices are actually being used.
Fifty-five percent of Fortune 100 companies now mandate five-day attendance, up from just 5% in 2023. Enforcement is up, too: 37% of companies are actively tracking attendance, more than double the rate from a year ago. And yet, when you look at actual attendance data across more than 200 million square feet of workplace sensor data, almost nothing has changed.
That gap isn't a coincidence. It's a signal.
The numbers behind the mandate surge
The shift toward full-week office requirements has been dramatic. According to JLL's 2025 Evolving Workplace research, five-day attendance mandates among Fortune 100 companies have jumped from 5% to 55% since 2023. That's not a gradual trend. It's a structural change in how large employers are approaching office policy.
At the same time, the way companies talk about these policies has changed. "RTO mandate" is giving way to softer language: vibrant office policy, workplace evolution, hybrid policy, activity-based work. The underlying requirement is the same. The framing is gentler.

Why enforcement isn't the answer
Between mid-2024 and Q3 2025, US companies increased required in-office days by 12%. Actual employee attendance over the same period increased by just 1-3%. Despite stricter mandates, the average number of days American knowledge workers work remotely has held steady at roughly 2.5 days per week since mid-2023, according to Nick Bloom's Stanford WFH Research.
VergeSense occupancy data tells the same story. Average capacity usage held between 9-11% throughout 2025, virtually unchanged from 2024's range of 8.5-10%. The policies got stricter. The office didn't get meaningfully fuller.
What did change is where the pressure went. Peak capacity usage jumped from 46-53% in 2024 to 52-60% in 2025. The same number of people are showing up, but they're converging into tighter schedule windows, which means the space plan is absorbing more pressure with no additional supply.
The Monday and Friday problem
Even among organizations seeing some uptick from enforcement, a consistent pattern holds: Tuesday and Wednesday carry the load, while Monday and Friday lag. Shortage rates on Tuesdays and Wednesdays hit 7% average, nearly double Monday's 4% and triple Friday's 2%.
Some organizations are addressing this through team-based rotation. Others are consolidating floors on Fridays to create a denser experience with fewer people. Neither approach fully closes the gap.
What the gap is actually telling you
The gap between mandated attendance and actual attendance isn't evidence that employees are defying policy. It's evidence that attendance behavior is shaped by factors policy alone can't control: commute burden, childcare, team culture, the quality of the in-office experience, and individual work patterns that vary week to week.
Some organizations are experimenting with financial incentives alongside mandates. One company tracked by the Flex Index is offering up to $2,000 per quarter in benefits credits for employees who come in five days a week, with a lower tier for two to three days. Whether that moves the needle more effectively than enforcement is a question the data will eventually answer.
For workplace and real estate teams, the more productive framing is this: if your attendance isn't matching your policy, your space planning assumptions are built on numbers that don't exist. VergeSense Predictive Planning, powered by the Large Spatial Model trained on 200 million square feet of real behavioral data, lets you model what your space actually needs to accommodate based on how people are actually showing up, not how policy says they should.
Planning for the attendance you have, not the attendance you mandated
The organizations navigating this environment most effectively aren't the ones with the strictest mandates or the most aggressive enforcement. They're the ones that understand the difference between the attendance they have today and the attendance they might have under different policy scenarios, and they can quantify what each scenario means for their portfolio.
That requires moving beyond static headcount assumptions and spreadsheet-based models. It requires the ability to run what-if scenarios against real behavioral data, understand which spaces are consistently under pressure and which are consistently underused, and make decisions that hold up when conditions change, as they will.
