The vast majority of guys understand that if a trip is labeled "disputed", then, their union has found fault with that trip, and so most guys won't fly it. The issue is that some guys are greedy enough to fly anything, and when these greedy/uninformed/unenlightened guys pick up these DP's and fly them for 3 consecutive months, the trips then automatically become "undisputed" and will then be built into one of our lines, thereby forcing a "normal" guy to fly it, while at the same time, eroding just a little more control from our SIG group. Those guys are the watchdogs of our while-working quality of life, and as such should be supported to the Nth degree. Guys flying these DP's are doing the exact reverse, to the detriment of the entire crew force.
