Sarah stared at her laptop screen at 8:47 PM, rubbing her tired eyes. The AI assistant had just helped her finish three client proposals in half the time it usually took. She should feel victorious, right? Instead, she found herself starting on two more projects she’d been putting off. “Since I’m being so productive tonight,” she thought, clicking open another document.
This scene plays out in offices across the world every day. Workers armed with artificial intelligence tools are discovering a troubling paradox: the technology meant to make their jobs easier is actually creating more work, not less.
A groundbreaking new study reveals that AI extra work has become an unintended consequence of workplace automation. Instead of the promised relief, employees are finding themselves trapped in a cycle of increased productivity demands and longer working hours.
The Berkeley Study Exposes AI’s Hidden Productivity Trap
Researchers from Berkeley Haas School of Business spent eight months tracking nearly 200 employees at a major US tech company. The study, running from April to December 2025, gave workers access to ChatGPT-style AI tools without requiring their use.
What they discovered challenges everything we thought we knew about AI in the workplace.
“Employees worked faster, took on more tasks and stretched their working day — often without being asked to and without realizing the long-term cost,” explains lead researcher Dr. Martinez Chen.
The phenomenon isn’t just about speed. Workers experienced what researchers call “work intensification” — a dangerous expansion of both the pace and scope of their daily responsibilities. AI tools made individual tasks quicker, but paradoxically led to longer overall working days.
Most surprisingly, this AI extra work appeared completely voluntary. No managers demanded overtime. No policies changed. People simply felt empowered to do more, creating an illusion of choice while falling into patterns that could harm their health and well-being.
Breaking Down the Numbers: How AI Actually Changes Work Patterns
The data reveals stark changes in how people approach their jobs once AI tools become available:
| Work Pattern | Before AI Tools | After AI Tools | Change |
|---|---|---|---|
| Average daily work hours | 8.2 hours | 9.4 hours | +1.2 hours |
| Tasks completed per day | 6.3 tasks | 8.7 tasks | +38% |
| After-hours work sessions | 2.1 per week | 4.6 per week | +119% |
| Weekend work frequency | 23% of employees | 67% of employees | +191% |
The researchers identified several key behaviors that contribute to this AI extra work phenomenon:
- Task Multiplication: Completing work faster led people to immediately take on additional projects
- Scope Creep: AI tools made previously difficult tasks seem manageable, expanding job responsibilities
- Blurred Boundaries: The ease of AI-assisted work made it tempting to continue working during personal time
- Perfectionism Amplified: AI tools enabled endless refinement and revision of work products
- Opportunity Anxiety: Fear of missing out on AI-enhanced productivity gains drove longer hours
“People told us they felt more capable and energized by their AI tools,” notes Dr. Chen. “But they were also working 15% more hours per week without realizing how it was affecting their lives.”
The study tracked physical and mental health indicators throughout the eight-month period. Stress levels increased by 23%, sleep quality decreased, and self-reported work-life balance satisfaction dropped significantly among heavy AI users.
Why This Matters for Everyone in the Modern Workplace
This research isn’t just academic curiosity. It reveals a fundamental shift happening right now in offices, home workspaces, and co-working environments worldwide.
The AI extra work phenomenon affects different types of employees in distinct ways. Knowledge workers face the biggest impact, as AI tools are most effective for writing, analysis, research, and communication tasks. Customer service representatives, marketing professionals, and consultants report similar experiences to those in the Berkeley study.
“We’re seeing a new form of digital overwork that feels voluntary but creates the same health risks as traditional burnout,” warns workplace psychology expert Dr. Rebecca Torres.
Managers and company leaders need to recognize that increased output doesn’t necessarily mean improved employee well-being or sustainable productivity. The Berkeley researchers found that while short-term performance metrics improved, indicators of long-term job satisfaction and retention showed concerning trends.
Several companies are already implementing “AI boundaries” to prevent this extra work spiral:
- Setting limits on after-hours AI tool access
- Tracking total work hours rather than just task completion
- Training managers to recognize signs of AI-driven overwork
- Creating explicit policies about workload expansion
The broader economic implications are significant too. If AI extra work becomes the norm, it could undermine the technology’s promise to improve work-life balance and reduce job stress. Instead of creating more leisure time, AI might inadvertently intensify the pace of modern work culture.
“Companies adopting AI tools need to actively protect their employees from productivity addiction,” suggests Dr. Chen. “The technology is powerful, but it requires conscious management to prevent it from consuming people’s lives.”
For individual workers, awareness is the first defense. Recognizing the psychological pull of AI-enhanced productivity can help people set healthier boundaries. The Berkeley study participants who maintained the best work-life balance were those who consciously decided when to stop working, regardless of what their AI tools could help them accomplish.
As Sarah discovered months later, the real skill isn’t learning to work faster with AI—it’s learning when to stop working altogether.
FAQs
Why do people work more hours when AI makes tasks faster?
AI tools create a psychological effect where faster task completion leads to taking on additional work rather than finishing the day earlier. People feel empowered to accomplish more, often without realizing they’re extending their working hours.
Is this AI extra work phenomenon happening in all industries?
The effect is strongest in knowledge work environments where AI tools are most applicable, such as writing, analysis, and communication tasks. Manufacturing and service industries show less impact currently.
Can companies prevent AI-driven overwork among employees?
Yes, by implementing explicit policies about work hour limits, monitoring total working time rather than just output, and training managers to recognize signs of AI-enhanced burnout.
Do AI tools actually reduce job satisfaction over time?
The Berkeley study suggests that while AI tools initially boost feelings of capability, extended use leading to work intensification can decrease long-term job satisfaction and work-life balance.
What can individual workers do to avoid AI extra work traps?
Set clear stopping times regardless of AI capabilities, consciously limit after-hours tool access, and focus on completing assigned work rather than expanding task lists just because AI makes more work possible.
Are there any benefits to AI-enhanced productivity in the workplace?
AI tools can genuinely improve work quality and reduce time on routine tasks when used with proper boundaries. The key is maintaining conscious control over workload expansion and time management.
