I never said they didn't have good ideas, I said that they can have some that are impractical. Why are 99% of them ignored? They are narrow in focus and don't take into other factors into consideration. The gains in one area (service, for instance) are more than offset by losses in another (SPH). Or vice versa. Or this guy wants his route adjusted to get more hours. OK, but it hurts the station in P/FTE and doesn't give us any gains in SPH or service. And my personal favorite, the courier who always makes service and goal who swears that his area is too big for him to make service and goal and he wants it restructured. "We can hire a PT courier to take what I bleed off." Yeah.
All of the above X 100. They aren't necessarily bad idea, just narrow.
