What changes

Weekly 1:1s are often associated with a 10–22% relative reduction in regrettable attrition compared with monthly check-ins.

When this tends to work

• Conditions similar to: Teams of 5–15 reports, tech and professional services, 2020–2025
• You can measure Regrettable attrition within 6 months reliably
• The intervention is implemented consistently, not half-measured

When to be careful

• Your audience or product differs materially from the cited context
• Compliance costs or second-order effects outweigh the lift
• Evidence label is estimate—treat wide ranges as planning bands, not promises

Practical takeaway

Use the cited range for prioritization and test design. Verify against your own data before scaling.
