Do Don't
  • Get at least 7 hours sleep before starting a night shift.
  • Eat light, balanced meals and stay hydrated throughout the shift.
  • Take scheduled breaks in a well-lit rest area during the night.
  • Report to your supervisor if you feel too tired to work safely.
  • Plan a safe journey home — consider a nap before driving after a shift.
  • Use bright lighting in work areas to help maintain alertness.
  • Rotate demanding tasks and share high-concentration work across the team.
  • Follow the agreed shift pattern and rest period requirements.
  • Use blackout blinds and a cool room for daytime sleeping.
  • Look out for signs of fatigue in your workmates and speak up.
  • DON'T work consecutive night shifts beyond the agreed maximum rotation.
  • DON'T rely on caffeine alone to stay alert through a night shift.
  • DON'T drive home if drowsy — rest first or arrange alternative transport.
  • DON'T eat heavy meals during the shift — they increase drowsiness.
  • DON'T skip breaks or rest periods during the night.
  • DON'T operate plant or machinery if you feel too tired to concentrate.
  • DON'T ignore signs of fatigue in yourself or your workmates.
  • DON'T use phone screens before trying to sleep after a shift.
  • DON'T volunteer for overtime if you have not had sufficient rest.
  • DON'T assume you can push through tiredness — fatigue impairs judgement.
