...an STA driver.
The men and women behind the wheel of the bus are under pressure to stay on schedule. That's as it should be, of course.
But they are also encouraged to wait for late arrivals who are on their way to a bus stop. Naturally, most drivers would like nothing better than to give stragglers time to make it to the bus. But if you do that several times you quickly find yourself running late. And that's not good.
I suppose many of us face push/pull conflicts in our jobs. But the prospect of having to choose between being seen as a heartless bad guy or messing up the route schedule seems like something that would really wear you down after a while.
