Re: How about construction then?
The mining companies did a *lot* of trials and analysis, and found that men in general are heavier on the throttle, which puts more wear on the tyres. Since the main cost associated with the big mining trucks is tyre wear, the hiring companies were instructed to pick the candidates with the lighter touch, which was predominantly the females in each intake. If you're only picking 3-5 candidates, and there are 60 applicants, even if only 10% are female, you'll get a lot more coming through the system.
Yes, a driver might earn $100,000/yr, but each tyre on a big caterpillar is currently costing between $90-150,000 and you need 6 on a truck.
Apparently underinflation also burns up to 15% of tyre life - it's something they *really* pay close attention to.
