28 problems carry work and worker safety

Labor problems center on the gap between how fast work hurts people and how slowly we measure it: silica dust exposure assessed by eight-hour filter samples whose results come back days later, proximity warning systems on construction sites with false-alarm rates above 90 percent — so workers tune them out, scaffolding that kills hundreds a year because nothing monitors its load during construction. A smaller set covers who gets access to work's tools at all, like the widening gender gap in mobile money accounts.
