Worked with PBS in the past.
It largely depends on programmed parameters and restrictions.
Where I was, it only benefited the very senior 20-30%.
The middle 30% was heavily dependent on what the top 30% would pick.
The bottom 40% was mostly unhappy.
Forget conflicts of any kind.
Less staffing, slower movement.
I would NEVER vote for PBS.

Green days are great while they last...
I believe the only restriction is a max of 25% red days per month.
CS can pick every single one of those days (weekends, holidays)

More efficient pairings, better daily credit, should be a priority.

Reserve rules need improvement and adherence to.
Currently there is no call out list.
CS has the "option" to chose who they call.
Either by credit, or by days available, you never know.
At most airlines, reserves know exactly what the call out priority is.

NO vote on the LOA.
Doesn't contract protect us from studying company manuals during distant learning?
