The research suggests that most employees are already over the productive threshold. Fellow’s 2025 data shows the typical employee spends 11.3 hours per week in meetings — approximately 28% of a 40-hour week. Research from Atlassian found that 68% of employees say they lack enough uninterrupted focus time due to meetings. A practical target: knowledge workers should have at least 4 hours of contiguous uninterrupted focus time per working day. Any meeting schedule that consistently prevents this should be audited for necessity and frequency.
