As an intern, I don't extend pilots, that's the full time scheduler's job, because extensions are complicated due to legalities, paperwork, etc.
Right now, pilots are required to 'give' 16 days to the company for flying per month. Ideally, it would be 16 away, 14 home in a 30 day month. But, there is a shortage of crew, and pilots are extended. (Some lines are broken down into two-8 day trips rather than one whole 16 day trip).
Max. extension per contract is two extra days, so a total 18 away, 12 home. Again, due to shortage of crew, extension is common (sadly).
Reseve coverage depends month to month. This month of July, we had a lot of reserve lines due to the military not getting back to us in time.
Reserves don't sit in JFK too long. I took a scan today on some schedules, and found that some sat maybe two days as reserve before being assigned to go on trips.
How many leave the company per month? I can think of two that have left this month. I think it was due to personal reasons. One left to enter a police academy, don't know about the other.
Here's the thing about retirements: Evergreen has about 18-20 captains retiring in the next 5 to 6 years or so. That number is a guesstimate, but there are a LOT. Considering there are only about ~225 captains, FOs, FEs combined, that figure represents about 20%-25% of cour captains retiring (due to age 60 rule only).
Then of course, I'm sure some pilots will leave the company for some other reasons.... I think in the past, some just couldn't take the 16-18 days away at a time, and they went to Jetblue (and other airlines).
I would love to fly for Evergreen. When other schedulers are looking for crews, and can't find someone to assign, I always joke that if I had a few thosand more hours, an ATP and a 747 type rating, I'd happily take that plane out of JFK
