Surely the clearest path to retaining only the best.
As much as I hate to admit it, the conversations that happen because I overheard another conversation a couple cubes over do have value.
If they have value to the company then how about sharing the costs of commuting? A 50-50 split seems reasonable to me. The company gets the value of those conversations, and the plebs get some help with all that fuel they now have to buy, at ridiculous prices due to high oil prices.
