The surprising connection between after-hours work and decreased productivity
Working beyond normal hours may be linked to lower productivity, according to a Slack survey that reports employees who feel obligated to work after-hours rate themselves about 20% less productive than those who log off on time. Commenters question the study’s reliance on self-reported data and correlation, suggesting that people who feel behind or are trapped in meeting-heavy or poorly managed environments are both more likely to work late and to feel unproductive. Many differentiate between coerced overtime and flexible or voluntary off-hours work, arguing that autonomy, focus time, and sane workload planning matter far more for output and well-being than raw hours logged.
Study quality and causation vs correlation
- Many commenters stress the data is self‑reported “productivity,” from an observational survey, so it can’t establish causation.
- Concerns: selection bias of volunteers, no clear handling of control variables or confounders, and vague definitions of “productivity.”
- Several argue that large sample size (10k) doesn’t fix bias or measurement problems.
Alternative explanations for after‑hours work
- Common hypothesis: people who feel behind or less productive compensate by working more hours; the lower “productivity score” may be cause, not effect.
- Others suggest personality traits (e.g., conscientiousness, high standards) could drive both lower self‑ratings and more after‑hours work.
- Some think low performers actually avoid extra hours; experiences differ.
Obligation vs choice; autonomy as key
- Thread repeatedly highlights the article’s caveat: feeling obligated to work after hours correlates with worse outcomes, while choosing non‑standard hours does not.
- Many say they’re most productive early mornings or late nights, and happily shift hours for life tasks, deep work, or side projects.
- Autonomy over schedule is framed as more important than clock time.
Interruptions, meetings, and Slack
- Several report higher productivity once Slack is closed; interruptions and constant pings are seen as major drains.
- Heavy meeting loads (e.g., >2 hours/day) are blamed for loss of focus and pushing real work into evenings.
- Suggested mitigations: strong documentation/handbooks, “office hours” instead of ad‑hoc questions, better async communication norms.
Culture, management, and “heroics”
- Many see chronic overtime as a symptom of poor planning, under‑staffing, or Scrum/sprint misuse, not personal heroism.
- Romanticizing people working at 1am is criticized as normalizing unhealthy expectations and wage‑dumping others.
- Others say they enjoy occasional late‑night tinkering when self‑directed, but agree this should not become a baseline expectation.
Individual differences and neurodiversity
- Some describe only being able to focus once everyone leaves, or sitting in a “ready” state during the day.
- There’s debate over whether this is ADHD, a reaction to modern interruption‑heavy environments, or both.
- Overall, commenters emphasize that people’s brains, optimal hours, and tolerance for meetings differ significantly.
