We had something at Southerjets called "trip parking".  Normal open time pickups are restricted by a cap, but pilot to pilot swaps are not. So you'd find something in open time that works, find someone with a hole in their schedule, do a PtP swap with one of your other trips (which would drop you below the cap), pick up the trip out of open time, then swap your trip back from your buddy.  Instant over-the-cap schedule adjustment. Under this system, PtP straight drops (where you just dump a trip into swap board for pickup) are like gold, because the cap doesn't apply to PtP swaps.  Back during the merger trauma, I had people call me after doing a straight drop into open time (permitted, assuming reserve coverage), and holler at me because they could have had the trip over the cap. Seriously...people who don't know me from Adam, called and squawked at me for how I adjusted MY schedule.
Soooo....anyway...it became pretty high profile, and during that time, here are the conversations I've had with people:
"Circumvents the intent of the contract"
"But with the pay cuts, I need to feed my family"
"Abrogates seniority"
"It's legal, tough turnips" (yup, that's the actual word used)
"With the type of trips on XYZ airplane, its the only way to make over X"*
* means I got this one multiple times, and generally X was > 90 hours
"Pilots A, B & C are running these trips in a circle. Open time never filters down"
You're the rep. What do you do?
A) Put in further restrictions, certain to earn you the ire of those who like it
B) Don't restrict it, and continue to get hammered by people pissed at it.
C) Don't think about it, but collect your flight pay loss for going to the MEC meeting anyway, because you have good hair and look good in a picture.
