When Long Hours Become a Hazard

Grain moves around the clock. Trucks line up. Equipment runs longer. Weather creates pressure. Problems need to be solved quickly. Employees work earlier, stay later, and often repeat that schedule for days or weeks at a time.

The industry’s ability to respond to those demands is impressive. But there is a point when working longer stops helping and starts creating additional risk.

Fatigue is a workplace safety hazard, and harvest creates nearly perfect conditions for it.

NIOSH identifies extended work hours, nonstandard schedules, physically or mentally demanding tasks, stress, and hot working environments as factors that can contribute to worker fatigue. Fatigue can slow reaction time, reduce concentration, limit short-term memory, and impair judgment.

In grain handling, where employees work around moving vehicles, conveyors, augers, railcars, grain bins, elevated surfaces, and other serious hazards, those effects matter.

Why Harvest Creates a Perfect Storm for Fatigue

Agriculture has a unique relationship with the clock.

A hospital, factory, or warehouse may have relatively predictable shifts. Harvest doesn’t always provide that luxury. Weather, crop conditions, equipment availability, transportation, storage capacity, and customer demands can dictate when the work needs to happen.

Agriculture, forestry, and fishing are industries where employees work extremely long hours over days or weeks during peak seasons such as harvest. Researchers note that more work is needed to understand and address the risks associated with these extreme schedules.

For grain operations, fatigue may be compounded by:

  • Extended shifts and consecutive workdays
  • Early mornings and/or overnight work
  • Physically demanding tasks
  • Repetitive work
  • Increased truck and equipment traffic
  • Heat and changing weather
  • Stress and time pressure
  • Seasonal or less-experienced employees
  • Reduced opportunities for adequate sleep and recovery

Any one of these factors can create challenges. During harvest, employees may experience several simultaneously.

Fatigue Is More Than Feeling Tired

Most people know what being tired feels like. That familiarity can make fatigue easy to dismiss. The problem is that fatigue can affect the abilities employees rely on to keep themselves and their coworkers safe.

According to the CDC, workplace fatigue can slow reaction times, reduce attention and concentration, limit short-term memory, and impair judgment.

Consider what those effects could mean during harvest. A truck driver reacts a little slower. An employee overlooks a step in a lockout procedure. An equipment operator loses track of a coworker’s location. A worker makes a poor decision during a bin-entry situation. Someone climbing a ladder loses focus. A supervisor working long hours misses a hazard that would normally stand out.

The concern isn’t simply that an employee feels tired. It’s that fatigue can affect the decisions and reactions required to perform hazardous work safely.

Recognizing Worker Fatigue

Fatigue won’t necessarily look the same in every employee. Supervisors and coworkers should watch for changes in behavior and performance, particularly as shifts become longer and harvest progresses.

Potential warning signs may include:

  • Reduced alertness
  • Slower reaction time
  • Difficulty concentrating
  • Forgetfulness
  • Poor communication
  • Irritability
  • Reduced coordination
  • Repeated mistakes
  • Poor decision-making
  • Unusual risk-taking
  • Difficulty keeping eyes open or frequent yawning

Employees should also be encouraged to recognize these warning signs in themselves. Creating that awareness is important because admitting fatigue can be difficult in industries that pride themselves on hard work and getting the job done.

Don’t Make Fatigue a Badge of Honor

One of the biggest challenges with harvest fatigue may be cultural. Long hours are expected. Stories about working until two or three in the morning can become a point of pride. Employees may hesitate to say they’re too tired because they don’t want to disappoint coworkers or appear unwilling to do their share.

That mindset deserves attention. Working hard and working safely are not competing values.

A fatigued employee who recognizes that they can no longer perform a task safely isn’t demonstrating weakness. They’re recognizing a hazard.

Management sets the tone. If employees believe they’ll be criticized for reporting fatigue, they’re less likely to speak up. If supervisors routinely discuss fatigue alongside other harvest hazards, employees are more likely to recognize it as a legitimate safety concern.

Build Fatigue Management Into Harvest Planning

Fatigue shouldn’t be addressed only after someone makes a mistake.

Before and throughout harvest, management should evaluate how work schedules, workloads, staffing, and operating conditions could contribute to fatigue.

NIOSH has historically recommended providing adequate protected off-duty time so workers have an opportunity to obtain sufficient sleep. It also notes that frequent brief rest breaks during demanding work can be more effective against fatigue than only a few longer breaks.

Practical strategies can include:

Plan staffing before peak periods. Anticipate when extended hours are likely and determine how the workload can be distributed.

Provide routine breaks. Employees need opportunities to rest, hydrate, eat, and mentally reset.

Pay attention to consecutive long shifts. Fatigue can accumulate. An employee’s condition on the fifth long day may be very different from the first.

Rotate demanding or monotonous tasks when practical. Repetitive work and prolonged physical or mental demands can contribute to fatigue.

Communicate at shift changes. Important safety information can be lost when tired employees are handing responsibilities to another crew.

Encourage employees to report fatigue. Workers should know that speaking up about their ability to perform a task safely is expected.

Watch the drive home. Fatigue doesn’t disappear when employees clock out. NIOSH warns that work-related fatigue can extend beyond the workplace and create risks when fatigued employees drive on public roads.

Supervisors Play a Critical Role

During harvest, supervisors should pay attention to more than production numbers. They should know who has been working extended hours, which employees are performing particularly demanding tasks, and whether someone’s behavior or performance has changed.

A simple conversation can be valuable:

  • How are you doing?
  • How much rest did you get?
  • Do you feel comfortable performing this task safely?
  • Do you need a break?

These aren’t signs that management is lowering expectations. They’re part of identifying a workplace hazard before it contributes to an incident.

Fatigue management works best when responsibility is shared between employers and employees. NIOSH specifically recommends that employers and workers work together to identify fatigue risks and implement strategies to manage them.

Don’t Let the Harvest Schedule Eliminate Safety Training

When everyone is busy, safety meetings and training can be among the first things pushed aside. That’s exactly when they may be needed most. If a traditional classroom session isn’t practical, use short pre-shift or toolbox or tailgate discussions to address the hazards employees are likely to encounter that day.

  • Spend five minutes discussing fatigue.
  • Review a recent near miss.
  • Talk about truck traffic.
  • Reinforce lockout/tagout.
  • Discuss grain entrapment.
  • Remind employees about communication around mobile equipment.

A short, relevant conversation can keep safety in focus without bringing harvest to a halt. Safety Made Simple has previously recommended maintaining routine safety training throughout harvest and using brief pre-shift meetings when longer classroom sessions aren’t feasible.

Fatigue and Other Harvest Hazards Go Hand in Hand

Worker fatigue isn’t an isolated hazard. It can increase exposure to many of the hazards grain employees already face. That’s why fatigue prevention should be considered alongside training on topics such as (click to see the SMS course):

Grain Harvest Safety
Reinforce the hazards employees encounter during one of the busiest periods of the year.

Preventing Worker Fatigue
Recognize and be proactive towards the causes and symptoms of fatigue. Encourage your team towards daily practices for combatting fatigue.

Housekeeping and Combustible Dust
Recognize the importance of consistent, effective housekeeping. Implement best practices that reduce the likelihood of danger.

Lockout/Tagout
Refresh employees on hazardous energy control before maintenance, cleaning, or equipment servicing.

Buried in Grain: Grain Entrapment and Engulfment
Help employees recognize the hazards associated with flowing and stored grain and reinforce safe practices before entry becomes an emergency.

Training doesn’t make employees immune to fatigue. It can, however, help ensure safe procedures remain familiar when employees are working under demanding conditions.

A Safe Harvest Requires More Than Getting the Grain In

There will always be pressure during harvest. Weather won’t wait. Grain has to move. Equipment will break. Customers will call. Employees will work longer than they do during other parts of the year.

Those realities make fatigue management more important, not less. Supervisors should plan for it. Employees should be trained to recognize it. Coworkers should watch out for one another. And organizations should create an environment where someone can acknowledge fatigue before impaired judgment becomes an injury.

As Joe Mlynek emphasizes throughout his harvest safety training, the goal isn’t simply to get through harvest. It’s to get through harvest safely.

Because the number of bushels moved will eventually be forgotten. Sending everyone home safely won’t be.
