The Monday nightmare and the impossible Tuesday after a holiday would be better if we had nightmares on Monday, Wednesday, and Friday? I fail to see the logic.
Which carriers would you have work in the plant? Rural carriers? City Carriers? Both? Do we require carriers from distant areas to commute in to the plant from 70 miles away or just those whose offices are closer? Do we work some of them at night one day and put them on the road delivering mail the next day when they are sleepy from the shift change? Are you trying to cause traffic accidents? Do you really want to put a policy into place that contributes to carriers running over small children while delivering mail?
Your ideas are not well thought out.
