Nice idea because that guy deserves it but there are two things to keep in mind with that strategy. 1. It is going to cost you 10 hours of pay to "stick it" to that guy, and 2. that guy has another 4X10 route to run so a swing is probably going to run your route. So maybe not such a good idea after all.Just call in sick the day after your day off and that guy can be elected to run your route with all those "problem packages" he left under the belt the day before.
