# Different worker segments leave for different scheduling reasons

Treating a workforce as a monolith leaves retention gains untapped, because different employee demographics value different scheduling features.

- **Part-time and newer employees** are most negatively affected by **physical fatigue** factors: short rests between shifts (including [[concept-clopenings|clopenings]]), long strings of consecutive workdays, and unstable start times.
- **Full-time and longer-tenured employees** are more sensitive to **fairness** and **consistency**: they care deeply about whether their schedules are equitable relative to peers and whether changes are communicated routinely.

This segment sensitivity maps directly onto the [[concept-scheduling-quality-dimensions|five dimensions]] and complements the store-format ([[claim-store-format-differences]]) and regional ([[claim-regional-labor-markets-dictate]]) moderators. It is the rationale for segmenting data by worker group in [[action-mine-workforce-data]].

**Confidence: high** · **Testable: yes.** **Enrichment:** The general principle that effects differ by segment is supported by the authors' own method description (segment-level LASSO). The precise mapping of *fatigue → part-time/new* and *fairness → full-time/tenured* appears in the full article and is plausible but not independently verifiable from public snippets.
