The number is staggering but well-documented: executives spend an average of 23 hours per week in meetings, according to research published by Harvard Business Review. In the 1960s, the average was 10 hours. That is a 130 per cent increase over six decades, and the trajectory is accelerating — meetings increased a further 13.5 per cent since 2020 alone according to Microsoft Work Trend Index. When more than half your working week is consumed by meetings, the question is not whether this is sustainable — it is clearly not — but how modern business arrived at a state where leaders spend the majority of their time talking about work rather than doing it.

The 23-hour meeting average reflects a cultural shift from decision-making to consensus-seeking, from trust-based management to visibility-based management, and from focused leadership to reactive attendance. The data shows this trend is accelerating and is a primary driver of executive burnout and declining strategic capacity.

The Data Behind the 23-Hour Average

Harvard Business Review's research tracks executive meeting time across decades, showing steady growth from approximately 10 hours per week in the 1960s to 23 hours by the 2020s. The growth is not uniform — it accelerated during periods of organisational complexity, technological change, and cultural shifts toward collaborative work styles. The average professional now attends 62 meetings per month according to Atlassian, which for senior leaders translates to even higher meeting loads.

Microsoft Work Trend Index data adds granularity: meetings increased 13.5 per cent since 2020, with the average Teams meeting lasting 35 minutes. The Doodle State of Meetings Report finds that only 50 per cent of meeting time is considered effective by attendees. Combining these figures suggests that executives spend approximately 11.5 hours per week in meetings that even the participants consider unproductive.

Unnecessary meetings cost US companies $37 billion annually according to Microsoft. The per-executive cost is measured in strategic capacity rather than dollars — 23 hours of meetings leaves approximately 17 hours in a standard 40-hour week for actual work. When meeting recovery syndrome adds 23 minutes of refocusing time per meeting, the actual productive time shrinks to perhaps 8 to 10 hours.

What Changed Since the 1960s

Several structural changes drove the meeting explosion. First, organisational hierarchies flattened, creating more lateral relationships that require coordination meetings rather than top-down directives. Second, matrix management structures created dual reporting lines that double the coordination requirement. Third, the rise of knowledge work eliminated the visible output that manufacturing provided, creating a management anxiety that meetings were designed to address.

Technology accelerated the trend. Calendar sharing made booking meetings frictionless. Video conferencing eliminated the travel cost that previously constrained meeting volume. Collaborative tools created expectations of constant availability that translated into constant meetings. Each technological innovation reduced the barrier to scheduling meetings while doing nothing to evaluate whether those meetings were necessary.

Cultural shifts completed the transformation. The move from autocratic to participative management created expectations of inclusion that manifested as meeting invitations. The fear of excluding someone from a decision produced meeting guest lists that grew beyond utility. The shift from trust-based to transparency-based management created demand for status meetings that served oversight rather than coordination.

The Productivity Paradox the Data Reveals

The 23-hour meeting average creates a profound productivity paradox. Meetings are ostensibly held to improve coordination, alignment, and decision quality. But the MIT Sloan study demonstrating that reducing meetings by 40 per cent increased productivity by 71 per cent proves that the aggregate effect of current meeting volumes is productivity destruction, not enhancement.

Stanford research on diminishing returns past 50 hours provides the individual dimension. CEOs working 62.5 hours per week — with 23 of those hours in meetings — are producing their strategic work in the margins, often during evenings and weekends when cognitive capacity is lowest. The meetings that are supposed to improve decision-making are displacing the focused thinking time that actually produces high-quality decisions.

71 per cent of senior managers say meetings are unproductive and inefficient according to HBR. The leadership consensus is clear: the people attending the meetings agree they are wasteful. Yet meeting volume continues to increase, creating a collective action problem where everyone recognises the waste but nobody acts because the cultural pressure to attend outweighs the individual benefit of declining.

The Burnout Connection

The correlation between meeting volume and burnout is strong and well-documented. Executive burnout has increased 32 per cent since 2020 according to Harvard Business Review — the same period during which meetings increased 13.5 per cent. Only 21 per cent of executives feel energised at work according to McKinsey. Deloitte finds that 77 per cent have experienced burnout. The meeting-burnout connection operates through multiple mechanisms.

First, meetings consume the time available for recovery. When meetings fill the entire workday, real work is pushed to evenings, which pushes sleep later, which degrades recovery. RAND Europe estimates sleep deprivation costs the UK economy £40 billion annually, and meeting-driven overwork is a significant contributor. Second, meetings create cognitive fragmentation that is itself depleting — the constant context-switching between different topics and audiences consumes more energy than sustained focused work.

Third, meetings create the illusion of productivity that masks strategic stagnation. A leader who spends 23 hours in meetings feels busy and productive, but the business may be making fewer high-quality decisions, pursuing fewer strategic initiatives, and developing less innovation than it would with a leader who had 23 fewer hours of meetings and 23 more hours of focused strategic work.

What the Research Says About Optimal Meeting Time

While no single study defines the optimal number of meeting hours per week, the aggregate research suggests that most leaders could reduce meetings to 10 to 15 hours per week — approximately the 1990s level — without negative consequences and with significant positive effects on productivity, decision quality, and personal wellbeing.

The MIT Sloan study's finding that a 40 per cent reduction produced a 71 per cent productivity gain provides the strongest evidence. A 40 per cent reduction from 23 hours brings the meeting load to approximately 14 hours — well within the range where research suggests meetings provide net positive value. Below this threshold, meetings serve genuine coordination and decision-making functions. Above it, they create the diminishing and eventually negative returns documented across multiple studies.

Burnout costs UK employers £28 billion annually according to the CIPD. Meeting reduction is one of the most cost-effective interventions available because it simultaneously recovers time, restores cognitive capacity, improves decision quality, and reduces burnout risk. The data is unambiguous: 23 hours per week in meetings is far more than the evidence supports as productive, and the gap between current practice and optimal practice represents an enormous opportunity.

Moving From Data to Action

The data on meeting overload is clear, consistent, and compelling. The challenge is not informational — it is organisational. Converting the data into action requires leaders who are willing to challenge the cultural norms that created the 23-hour average and model alternative approaches.

Start with your own calendar. Apply the NOSTUESO filter. Default to 25-minute meetings. Replace information-sharing meetings with written communication. Block protected time for focused work. Decline meetings where your presence is not essential. Each action reduces your personal meeting load while creating cultural permission for others to do the same.

The executives of the 1960s spent 10 hours per week in meetings and built the business infrastructure that modern companies inherited. The suggestion that modern leaders need 23 hours of meetings to accomplish equivalent or lesser outcomes is not supported by the evidence. The data tells a clear story: we are meeting more and accomplishing less. The leaders who act on this data will outperform those who continue to accept the status quo.
