Musculoskeletal disorders (MSDs) — injuries to muscles, tendons, nerves, and joints from repetitive strain, awkward posture, and heavy lifting — are the single largest category of lost work days in NYC construction. They develop quietly over months and years, then become debilitating. A worker who finishes their career with a destroyed back, chronic shoulder pain, or carpal tunnel syndrome did not have to — most MSDs are preventable with the right work practices and equipment.

• Forceful exertion: Heavy lifting, pushing, and pulling against resistance. Reduce through mechanical assists, team lifts, and breaking loads into smaller units
• Repetitive motion: Repeating the same motion hundreds or thousands of times per shift. Rotate tasks where possible; take micro-breaks to relieve specific muscle groups
• Awkward posture: Working overhead, kneeling, twisting the torso, or reaching far from the body. Raise the work surface, use a raised knee pad, reposition the material instead of the body
• Sustained/static posture: Holding a single position without movement. Alternate between standing, kneeling, and stretching positions during long tasks

• Request ergonomic aids: knee pads for floor work, anti-fatigue mats for standing tasks, tool balancers for overhead tool use, extended-handle tools for floor or low-level work
• Stretch before and after demanding tasks — particularly shoulders, lower back, and wrists for the specific work you perform
• Report early symptoms: tendon soreness, numbness, tingling, or recurring joint pain are early MSD warning signs. Report to the SSM and seek evaluation — don't wait until you can't work
