Faintings by factory workers are a regular occurrence here. They do all kinds of tests, improve ventilation, advise the workers to eat better, get more sleep, whatever, but I don’t think that’s going to change a thing. For whatever reason, it’s a cultural phenomenon with its own expectations. One young woman faints for some reason–or maybe just suggests that she feels funny or something–and that is the trigger, giving permission for everyone else to “faint” too. There’s probably no problem. It’s just what you’re supposed to do. I suspect the best response is to have a section of clean factory floor and just lay them side by side until they decide they’ve been on the floor long enough and them let them go back to work. Taking them to clinics, etc., probably doesn’t help and just perpetuates the problem.
