What you consider to be spying, I consider to be normal. When your manager is sitting in the passenger seat of a package car, you're going to drive a LOT differently than if there is no manager in the passenger seat of your package car.
Ironically, if you follow the proper habits, you'll notice your manager by the 3rd stop.
I do the job safely and properly, and therefore, I have nothing to worry about. That's why I wouldn't see a manager following me in his personal vehicle to be 'spying'.
I would just wave after every stop and later embellish the three point contact while staring at him. Or I would stop at the coffee shop during my break, get him a coffee, then walk up to his vehicle.
Haha! Living in Boston, you can probably tell us first hand what happens if the police arrive full force with the bomb squad only to find out.....
You get a bill for double what it actually cost the city!
no way in hell fedex express would follow their own drivers, unless there was an extremely compelling reason why. i can tell you that as a fact.
counting cars.. I can see it as possible, although I see no use of that data for a competing company; the number of cars rolling out of a center at a time means nothing if we don't know how many boxes are in those cars and what loops they're covering.
i bet you those people counting cars were from the transport ministry. but it could very well be fedex, after all, it's widely known that airlines do passenger counts in the gate areas of other airlines.
