Sooooo....
Can someone explain what you actually get paid?
Contract says they pay you for your vacation. So I assume that means you get 6 CH x # of vacation days. (so, 42 CH for a 7-day vacation)
You also get 24 CH for the buyback.
So far, we're at 66 CH.
Since your vacation is gone, you bid a normal 80 hour line and fly it.
Are you going to get paid 66 + 80 = 146 CH for that month?
