Practical Ergonomics for the Office Workplace

The Business Case for Ergonomics

Musculoskeletal disorders (MSDs) — injuries affecting muscles, nerves, tendons, joints, and cartilage — account for a significant share of workplace injuries and workers' compensation costs. In office environments, these injuries typically involve the back, neck, shoulders, wrists, and hands, and develop gradually from repetitive motions, awkward postures, and sustained positions.

Effective ergonomic interventions reduce injury rates, decrease workers' compensation costs, lower absenteeism, and improve productivity. Many of the most impactful changes cost little or nothing.

Workstation Setup Fundamentals

Chair Adjustment

The chair is the foundation of an ergonomic workstation. A properly adjusted chair should allow:

• Feet flat on the floor or on a footrest, with thighs roughly parallel to the ground
• Two to three inches of clearance between the front edge of the seat and the backs of the knees
• Lumbar support that fits the natural curve of the lower back
• Armrests (if used) at a height that allows the shoulders to remain relaxed, not shrugged

Employees often do not know how to adjust their chairs. A five-minute demonstration of chair adjustment features is one of the most effective ergonomic interventions available.

Monitor Position

• The top of the screen should be at or slightly below eye level
• The monitor should be approximately an arm's length away
• The screen should be positioned directly in front of the user, not off to one side
• For dual monitors, position the primary monitor directly ahead and the secondary monitor adjacent and angled toward the user. If both monitors are used equally, center the seam between them

Keyboard and Mouse

• The keyboard should be at a height that allows the forearms to be roughly parallel to the floor with elbows close to the body
• Wrists should be in a neutral position — not bent up, down, or to the side
• The mouse should be at the same height as the keyboard and close enough that the user does not need to reach for it
• Consider providing keyboard trays for desks that are too high for comfortable typing

Laptop Users

Laptops are inherently problematic for ergonomics because the screen and keyboard are attached. When a laptop is the primary work tool, provide an external keyboard and mouse and use a laptop stand or monitor riser to raise the screen to eye level.

Beyond the Workstation

Movement and Breaks

Sitting in any position for extended periods contributes to discomfort and injury risk. Encourage employees to:

• Take brief micro-breaks (30 to 60 seconds) every 30 minutes to stand, stretch, or shift position
• Alternate between sitting and standing if sit-stand desks are available
• Walk to a colleague's desk instead of sending an email when practical
• Use break times for movement rather than remaining seated

Lighting

Poor lighting causes eye strain, headaches, and awkward postures as employees lean forward to see their screens. Ensure adequate ambient lighting and reduce glare on monitors by positioning screens perpendicular to windows and using blinds or shades.

Phone Use

Employees who frequently use the phone while typing or writing should use a headset rather than cradling the handset between the ear and shoulder. This simple change prevents significant neck and shoulder strain.

Implementing an Ergonomics Program

1. Conduct workstation assessments. Walk through the office and observe how employees are positioned at their workstations. Many issues are visually obvious — monitors too low, chairs poorly adjusted, keyboards at wrong heights.

2. Train employees. Provide basic ergonomic training that covers workstation setup, the importance of posture and movement, and how to request an assessment or equipment.

3. Respond to discomfort reports promptly. When an employee reports discomfort, conduct an individual assessment and make adjustments before a minor issue becomes an injury claim.

4. Budget for equipment. External keyboards, monitor risers, footrests, and headsets are inexpensive. Ergonomic chairs cost more but last years and pay for themselves in reduced injury costs.

5. Include ergonomics in new-hire setup. Assess and adjust each new employee's workstation when they start rather than waiting for complaints.

An ergonomics program does not need to be elaborate. Consistent attention to workstation setup, employee education, and prompt response to discomfort reports will address the vast majority of office ergonomic risks.
