One trick I heard about. If you can get the employee count up, you can get your reported injury rates down.
Ie, two warehouses, both doing 1 injury per 10,000 packages shipped. If one has double the employee count it can make some of the reported injury rates go lower. If you ever see 5 guys watching one guy dig a hole - that employer is going to have great injury rate reporting even if the guy actually digging a hole gets injured just as often as anyone else digging a hole. Not sure if they figured out ways of mixing in management / white color jobs into the warehouse numbers.
But I'm surprised no one discusses underreporting at smaller warehouses.
And comparing to retail workers at walmart also seems a bit weird?
