I am glad you mentioned area knowledge.
We have a new center manager who seems to have a different set of operating rules than our previous center manager's. His newest one is that we can all be directed to cover a route other than our bid route based on staffing needs and area knowledge; in fact, during the PCM last week, he mentioned my name, saying that I could be "asked" to go to Lake Placid, if needed. Keep in mind that I have not delivered a full route there in more than 10 years. We had two FT bid route drivers directed to cover routes other than their own this past week. They were not happy campers.
