AI might one day replace us all — for now though, humans still spend a lot of time cleaning up its mess, according to a Workday survey released Wednesday.

Why it matters: The promise of AI is that it makes work more productive, but the reality is proving more complex and less rosy.

Zoom in: For employees, AI is both speeding up work and creating more of it, finds the report conducted by HR software company Workday last November.

• 85% of respondents said that AI saved them 1-7 hours a week, but about 37% of that time savings is lost to what they call “rework” — correcting errors, rewriting content and verifying output.
• Only 14% of respondents said they get consistently positive outcomes from AI.
• Workday surveyed 3,200 employees who said they are using AI — half in leadership positions — at companies in North America, Europe and Asia with at least $100 million in revenue and 150 employees.
