The reason they are looking for volunteers is that this is against the law. A bit similar to the one in seven that you signed away in return for NEGOTIATED FTL’s.
Once they tore up the FTL’s/RP’s, every pattern over 6 days has technically been illegal.
Now, everything goes out the window and you will sign a waiver that says you agree to the proposed 5 weeks on, 2 weeks off.
After the whole debacle is over they will use that as a precedent to argue that pilots really don’t need a break or see their family.
Good luck to you all!
