Claim

The trials lack a randomized control group and most participating firms have no objective productivity metric; lead researcher Juliet Schor characterized the results as self-reports of companies saying the innovation is working, and economists noted that the implied overnight productivity jumps are implausibly large.

4-day workweek productivity claims gather criticism (TechTarget)

No control group; productivity poorly measured; Schor calls results self-reports; Dean Baker calls a 25% overnight productivity jump 'impossibly great'; Hamermesh finds four-day workers earn less for the same hours, suggesting a productivity hit.
