I'm not sure how pay works for you guys at 9E and how it is going to work going forward with the JCBA, but I would be inclined to think that it might work similar to how we have it at XJ currently. Try to think of it in annual terms instead of a month by month basis.

At XJ, regardless of pilot status we are paid our 75/month on a bi-weekly scale. The math comes out to 75x12=900 hours per year. That 900 hours is divided by 26 (number of pay periods) which comes to 34.62 hours. Every check we get is paid at 34.62 hours regardless of how many days there are in the month. With bi-weekly pay, you end up twice a year having a month were you get three checks in one month. So if you want to get technical, at XJ we are paid 69.24 hours for 10 months of the year, and for two months we 103.86. The pro-rata portion for time missed is removed on the check (pay period closest to the end of the month) where our over guarantee is also paid out.

The math adds up to the same amount of money regardless of how many day there are in the month or how many you work them. And actually, you are coming out better by calling in sick for a day and only having them dock you 3.75 hours of pay.

11 days off x 12 months = 132 days off annually
365 - 132 days off = 233 days worked
900 hours / 233 days = 3.86 hours/day

Clear as mud?
