I don't think that you were accused of stealing a package, but rather stealing service. Unless the other driver coded out to break when he handled that package, the company paid him to handle it, the package took up room in a package car and the weight diminished the fuel efficiency. The argument I would offer is this. If I'm on break and buy a fountain soda and a candy bar, return to the building and give the candy bar to a coworker, would I be fired? Should I have paid the company to ship the candy bar? It's the same thing. So I guess they'll have to fire everyone. We all run errands for other drivers, with the hours we work, it's a necessity.
