I'm pointing out that whether or not the mgt is trying to screw the workers, the opaque approach with the "Communications Team" generated only suspicion about both what was happening and the intent of management.

Let's assume you are correct and the entire adjustment was pay neutral - the total payout to workers for an identical set of deliveries was identical to the penny, only redistributed favoring/disfavoring different mixes of cargo and mileage. Why is it to anyone's advantage to hide that fact?

In fact, if you are trying to incentivize different behaviors, the best thing to do is to provide ALL the information on the reward structure, so the drivers can immediately read and analyze it and immediately adjust their selections to implement the new system.

Instead, the only thing management generated was confusion, ,mistrust, and poor implementation of their goals. For me, this raises a legitimate question of whether management is simply incompetent, or if they are trying to hide something (i.e., they're taking money off the worker's table and trying to avoid telling them).
