Supervisors play a critical role in managing fatigue on the jobsite. By planning work effectively, monitoring workers for signs of fatigue, encouraging open communication, and adjusting work activities when needed, supervisors help reduce the risk of fatigue-related incidents. Workers should feel comfortable reporting fatigue concerns without fear of retaliation, allowing hazards to be addressed before they lead to injuries.
This toolbox talk reviews how supervisors can support fatigue management and how workers and supervisors share responsibility for maintaining a safe, alert workforce.
Why This Matters
- Supervisors help identify and manage fatigue risks before work begins.
- Open communication encourages workers to report fatigue concerns early.
- Proper scheduling and staffing reduce the likelihood of fatigue-related incidents.
- Monitoring workers throughout the shift helps identify changing conditions.
- Addressing fatigue proactively protects workers, equipment, and the project.
Common Fatigue Management Challenges
- Extended work hours or excessive overtime.
- Consecutive shifts with limited recovery time.
- High physical or mental workloads.
- Extreme weather increasing worker fatigue.
- Pressure to meet production schedules at the expense of rest.
- Workers hesitating to report fatigue concerns.
- Insufficient staffing for demanding workloads.
- Failing to reassess fatigue risks as work conditions change.
Safety Checklist
Supervisor Responsibilities
- Discuss fatigue risks during pre-job planning and daily safety meetings.
- Schedule work to allow for required breaks and reasonable recovery periods whenever practical.
- Monitor workers for signs of fatigue, including slowed reactions, reduced concentration, frequent errors, or unusual behavior.
- Adjust work assignments, staffing, or task rotation when fatigue risks increase.
- Encourage workers to report fatigue concerns promptly and respond appropriately.
- Review incidents, near misses, or changing work conditions for potential fatigue-related factors.
Worker Responsibilities

- Watch for signs of fatigue in yourself and your coworkers.
- Follow task rotation and fatigue management procedures when implemented.
- Report unsafe conditions or work schedules that may contribute to excessive fatigue.
Crew Talking Points
- What fatigue risks are present on today's job?
- Which tasks require the highest level of alertness?
- How should workers report fatigue concerns?
- What adjustments can be made if fatigue becomes a safety issue?
- How can supervisors and workers work together to manage fatigue?
- Speak up immediately if fatigue is affecting your safety or the safety of others.
Stop Work If
- A worker is too fatigued to safely perform assigned duties.
- Fatigue is impairing judgment, reaction time, or safe decision-making.
- High-risk work cannot be completed safely because of worker fatigue.
- Work schedules or changing conditions create unmanaged fatigue hazards.
- Adequate breaks or staffing are unavailable to safely complete the work.
- You are unsure whether fatigue is affecting your ability to work safely.
Final Reminder
Fatigue management is a shared responsibility. Supervisors should plan work to reduce fatigue risks, encourage open communication, and respond promptly to fatigue concerns. Workers should report when they are too fatigued to work safely, take scheduled breaks, and look out for one another. Addressing fatigue early helps prevent injuries and keeps the entire crew working safely.
