Crain's New York Business editor Greg David, a 22-year veteran of the magazine, was kicked upstairs earlier this month, and he's none too happy about it. "David is not going quietly," a tipster tells us, describing the atmosphere as "really horrific." Apparently there have been tears in the ladies room! Frankly, we would be kind of cranky ourselves if management declared us past our expiration date after 22 years. Yesterday, David fired assistant managing editor Carmen Fleetwood, but we hear the decision probably wasn't related&mdash the two often butted heads. Fleetwood hadn't been at Crain's long&mdash she joined the magazine in June after 13 years as a reporter and editor at Dow Jones Newswires.
