Scheduling your staff for the same shifts at the same times allows their bodies to establish a regular schedule. When a person gets into a normal rhythm, they can sleep better and train themselves to be more alert when awake, resulting in less fatigue and improved productivity.
Workplace fatigue occurs when employees experience increasing difficulty in performing mental and physical tasks due to factors such as inadequate restorative sleep, health issues or emotional stress. Often affecting night shift workers and those with irregular schedules, chronic workplace fatigue can negatively impact mental, emotional, and physical well-being if not managed properly. Identifying and addressing fatigue is crucial for both employee health and overall job performance.

What Are Common Workplace Fatigue Risk Factors?
While workplace fatigue can be easy to dismiss early on, it can lead to more serious problems such as impaired functioning and chronic health concerns. For some employees, admitting to work fatigue can be a challenge in itself — often due to a competitive work culture or fear of losing out on a promotion. Employers can even be complicit in perpetuating such fears, sometimes placing demands on employees to work beyond regular hours.
But workplace fatigue is a safety topic that must be identified and managed accordingly. Employers and employees alike should recognize the common risk factors associated with workplace fatigue, which can include:
- Fast-paced or mentally demanding work
- Irregular shift schedules or consecutive night shifts
- More than 50 average hours per workweek
- Bad sleep quality
- Boring, repetitive and monotonous work
- Physically demanding work
- Long commuting hours
- Personal health issues
- Little or no break time
- Stressful, noisy work environments
- Dim lighting or overly bright lighting
What Are Common Workplace Fatigue Symptoms?
Symptoms of workplace fatigue can surface at any point in an employee’s tenure, but they aren’t always easy for others to spot. Sometimes, workplace fatigue goes unrecognized until the employee experiences significant health problems or leaves due to burnout. Spotting signs of workplace fatigue early is not only an important factor in employee retention, but also in overall employee health.
Workplace fatigue symptoms can range from mild to severe, occasional to chronic and imperceptible to highly noticeable. They can surface as a direct result of workplace environmental factors such as working conditions, working hours, the nature of the work and others, and they can also be caused by more indirect factors such as sleep trouble or personal health problems. However, it’s important to remember that stress factors at work often affect every aspect of daily life.
With an attentive eye, symptoms of fatigue can be easy to recognize both in your work environment and those of others. Once you’re able to identify symptoms of work fatigue, you can begin to manage them.
Common symptoms of work fatigue include:
- Reduced alertness
- Slow reaction time
- Impaired memory and other cognitive functions
- Irritability
- Difficulty keeping your eyes open
- Impaired vision
- Loss of appetite
- Digestive problems
- Impaired decision-making
- Loss of situational awareness
- Isolation
- Performance decrement
- Falling asleep at work
- Loss of drive and motivation
- Depression
The Impact of Workplace Fatigue on High-Risk Industries
Workplace fatigue can affect workflow and productivity in any industry, but when it comes to industries with existing risks, it can become outright dangerous. Exhaustion often presents itself in a similar manner as alcohol and other depressants, so when a fatigued employee is working with heavy machinery or sensitive materials, it can create similar concerns. For most people, all it takes is about 21 hours without sleep to function at a level similar to if they had a blood alcohol content of .08, the legal qualifier for being drunk.
With such a comparison, it’s no wonder that the rate of accidents increases as workers report feeling more fatigued. The question then becomes how you can help mitigate these risks by learning how you can do more for your staff.
How Can You Mitigate Workplace Fatigue?
It is important for all employees to know the signs and symptoms of fatigue for self-recognition of fatigue, or recognition of fatigue in a co-worker.
Simply put, fatigue is fatigue; however, fatigue can either be work-related or non-work related, and one influences the other. The difference is that work-related fatigue needs to be managed by employers, while non-work related fatigue needs to be managed by the individual. For example, an employer can provide 16 hours between shifts, yet if an employee’s personal life only allows for 6 hours of sleep, that employee will be at an increased risk for fatigue and an incident or injury.
The long-term health effects of fatigue associated with shift work and chronic sleep loss may include heart disease, diabetes, high blood pressure, gastrointestinal disorders and depression. Of course, of equal concern are the near term safety consequences of fatigue, which would include decreased alertness, higher error rates, slowed reaction time, poor judgment of performance when assessing risk, inability to remember sequences of events, injuries and accidents.
Conducting Rigorous Fatigue Risk Assessments
In many cases, employers are limited in what they can do to prevent employee fatigue, especially as they have no control over the habits of their staff outside of the workplace. However, improving scheduling practices is one thing every employer can do to minimize the risk as much as possible. Take a look at your most vulnerable staff’s schedules and see if there are reasonable actions you can take, such as:
The longer a shift is, the more time an employee needs to recover from the strain. However, these same long shifts often mean they’ll have less time to recover after before they need to tend to their other responsibilities or return to the workforce for their next shift. In this way, limiting shifts to the traditional eight hours as much as possible can result in improved focus while staff is on the clock.
Sometimes, a closing shift followed directly by an opening shift cannot be avoided, but if there is any way to do so, you should. Giving your staff time in between their shifts to rest and tend to personal matters reduces the chance of them being fatigued on the job and increases their chances of staying focused and productive throughout their time at work.
Breaks are vital for staff to maintain the highest level of productivity and focus while on the clock. Encourage your workers to take breaks as needed during the workday. Some employers have even noted the value of allowing staff to take naps in between jobs to deliver a much-needed energy boost.
Implementing Fatigue and Accident Prevention Programs
Outside of your scheduling efforts, it may also be beneficial to implement accident prevention programs and training. We learn new information about workplace fatigue management every day, and it’s likely that your staff aren’t as informed as you are about the concept. The more they know and understand about workplace fatigue and how it affects their workflow, the more measures they can take to combat it.
For example, recent studies show that using better ergonomics in the workplace can reduce fatigue and minimize the risk of accidents. By publicizing this information to your staff, you can work together to identify areas in need of better ergonomic controls and directly apply their feedback in ways that make them feel more prepared for their jobs.
Creating a Fatigue Toolbox
Managing fatigue is an important component of creating and maintaining a healthy, productive work environment. Once workplace fatigue is identified, employers and employees alike need a structured plan of action for combatting workplace fatigue and preventing it from recurring. Having workplace fatigue management toolbox talks can help people on both sides of the fatigue safety topic equation.
Here is a toolbox for talking points on workplace fatigue that employers and employees can use to reduce workplace fatigue:
Employers
- Place a workweek limit of 55 hours per week
- Create a policy on second jobs, but compensate workers sufficiently
- Allow for adequate break time
- Encourage carpooling in case of drowsiness
- Eliminate repetitive, boring work
- Provide training to allow multitasking and effective job rotation
- Encourage healthy eating and an overall healthy lifestyle
- Check in with employees about workplace well-being
- Educate employees on fatigue causes and symptoms
- Optimize work conditions including ergonomics, lighting, glare and ventilation
- Incorporate weekly or monthly fatigue safety talks, or “fatigue safety moments”
Employees
- Give yourself enough time to ensure you get sufficient sleep
- Limit alcohol and caffeine consumption for better sleep quality
- Night shift workers need to maintain a strict routine for diet and sleep
- Incorporate daily exercise
- Arrive at work alert and ready to perform required tasks
OSHA Fatigue Management Plan
OSHA maintains its own handbook for guiding employers and employees on how to manage workplace fatigue symptoms and encourage safety in even high-risk locations. Over the years, they’ve created resources using risk management materials from a number of state and federal agencies to identify and ease fatigue-related hazards on the job. Their website is home to dozens of sources you can integrate into your own practices of managing stress and fatigue in the workplace.

Support an Integrated EHS/ESG Management System

While a Phase I Environmental Site Assessment (ESA) is a common method for identifying environmental liabilities during transactional due diligence, the ASTM International standard for Phase I ESAs (E1527-13, with proposed E1527-21 awaiting adoption) omits regulatory compliance from its scope. For properties containing operations that may be applicable to environmental compliance regulations, performing a limited environmental regulatory review can identify potential deficiencies with the environmental management of the facility. A limited environmental compliance review typically evaluates the presence of material findings that may exist in a facility’s management of its environmental compliance requirements. Material findings are defined as a condition of non-compliance that could necessitate expenditures, not including attorney fees or regulatory agency penalties, in excess of a specified dollar amount or materiality threshold. The materiality threshold is based on the client’s risk tolerance and is often in the range of $50,000. However, this amount is arbitrary and can be revised as appropriate. Non-material deficiencies, those identified below the materiality threshold, would still require action but are within the client’s risk tolerance.
