Let's say, at base, you have 100 employees - yes, we'll assume they all leave - but you've hired 100 more to keep the base at 100 employees (1/1 = 100%). So, in this scenario, having 200% turnover, you'd have to hire 100 people twice, 200 people, during the year to maintain those 100 jobs (200 leave; 100 jobs - 200/100 = 200%)... So you have a hundred, they leave, you hire another hundred, they leave and you hire another hundred. Now lets say USX has... 7000 drivers (for ease). This would mean they hire 14,000 drivers to maintain 7000 jobs (14000/7000 = 2, or 200%). To maintain their 7000 positions they have to hire 2 people for every 1 that leaves. That's a ton of turnover, even McDonald's does better (130%, or 4 hires for every 3 jobs, last I was aware). I hope that made sense...
