The problem isn't the number of draft/ava hours being flown. By themselves those numbers don't state much about the manning levels. The problem is we have too many guys doing the work of 1.5, 2, or 3 pilots. Its not the people conflicting and flying at 150% that are undermining efforts to achieve a TA. Its Mr.
"Capt/FO willing to extend" and the
Blue man 
group that are self dealing to the detriment of the group. We are contractually obligated to so many days. That should be the limit. NO ONE should be castigated for what they get paid on those days.
Let's stay focused.
The company will have to deal with us if we can just tell them NO. There is a labor shortage that isn't going to be resolved in the next 10 years. Automation won't save them nor will raising the retirement age. Anything that was true regarding the power dynamics between management and labor for the last 20 years is going to be upended going forward. No need to fear the NMB or capitulate because the RLA makes things hard. The numbers are on our side the baby boomers WILL exit the workforce. There aren't enough GEN Xer's to fill that gap and they did such a good job of marginalizing our profession that the pool of millennial candidates is abysmally small.
THERE IS A LABOR SUPPLY SHORTAGE
All the signs are there:
Carrier sponsored ab initio programs
Relaxed minimum flight hour requirements
Elimination of the College Degree
Cancelled flights
DECREASES IN SUPPLY DRIVE COSTS UP
All we must do is say NO! Not "I'll consider it", simply no. Then be a little patient.
