Claim LD03-SL-C06 (v1.0)
In a six-month randomized trial of an integrated AI assistant across 66 firms and 7,137 knowledge workers, workers who used it spent about two fewer hours a week on email, but the authors detect no shift in the quantity or composition of workers' tasks from individual-level provision, and no change in time spent in meetings.

| 14 | MAIN RESULT | Email time −1.4 hours a week intention-to-treat (−12%), about −2 hours (−17%) among users; less work outside regular hours; no detectable change in Teams meeting time (effects outside −0.01 to 0.21 hours a week ruled out) or in task composition; weekly use settled just under 40% of treated workers | — |

| 17 | VERIFICATION STATE | CONTENT VERIFIED | state: CONTENT_VERIFIED_PRIMARY · verified_by: UNKNOWN |
| 18 | LIMITATIONS | Telemetry measures time use, not output or quality; team-level effects may be undetectable because even high-saturation teams had about 39% of coworkers treated; the authors interpret the contrast between email and meetings as a difference between work individuals can change alone and work that needs coordination; three of the four authors are at Microsoft Research and the experiment was run by Microsoft with its customer firms | — |
