Warehouse work is measured in picks per hour, and that number is the whole story.
A picker doing three hundred picks an hour is doing two and a half thousand loaded grips in a shift, each one a lift, a carry and a place. Nobody would program that as training, and it runs five days a week.
What the tasks do
- Picking and placing. Repeated grip and lift, frequently at awkward heights — overhead or at floor level, both of which bend the wrist
- Box handling. Fingers hooked under a carton edge is a pinch grip carrying a heavy load. This is the position that causes most finger and hand problems in the trade
- Scanning. One finger on a trigger, thousands of times, usually the same finger
- Pallet trucks and cages. Push and pull force through the hands with the wrist in whatever angle the handle dictates
- Wrapping and taping. Repeated rotation under tension
- Cold stores. Same load, stiffer tissue, less sensation, harder gripping
Picks per hour is a hand metric. Everyone treats it as a productivity one.
What turns up
- Night numbness in thumb, index and middle: carpal tunnel syndrome
- Catching at the base of a finger, worst in the morning: trigger finger, the classic scanner-trigger and carton-hook injury
- Thumb-side wrist pain lifting with the thumb up: De Quervain’s
- Inner or outer elbow pain: golfer’s elbow or tennis elbow
- Little-finger-side wrist pain on rotation or when pushing a cage: TFCC injury
- Numbness in ring and little fingers: cubital tunnel
- Aching across the hands that builds through a shift: general overuse
Acute injuries too: a finger caught between a carton and a shelf edge is a crush injury, and rings plus moving equipment are how ring avulsion injuries happen. Take rings off for the shift.
What actually changes it
- Carry boxes with flat hands underneath, not fingers hooked over the top edge. Single biggest change available
- Use handholds and box cutouts where they exist, and ask for them where they do not
- Gloves that fit. Too tight costs force on every grip across a whole shift
- Alternate the scanning hand and the trigger finger where the system allows
- Keep loads between knee and shoulder height when you have a choice about which face of the pallet to work
- Rotate tasks. Pick, then pack, then replenish, rather than eight hours of one
- Warm hands in cold stores, with liners and warm-up time
Report it early
- Numbness that has stopped coming and going
- A finger that catches, locks or will not fully straighten
- Grip failing before the end of a shift
- Pain present at the start of a shift rather than building
- Any crush injury to a fingertip, including one that seems minor
These are reportable work-related conditions in most jurisdictions, and a record made early is worth more than one made after you go off sick. Returning to work after a hand injury frames the conversation around specific tasks rather than a blanket fit-or-unfit verdict.
The rate is set by the system. How you hold the box is set by you.
