Yep. When I was a reserve I never flew and neither did any of my crash pad roommates. Now that we all have lines none of us can ever drop anything or get any vacation requests approved due to insufficient reserve staffing.

I also never got a single early release request approved despite the fact that I once pointed out on the phone that I hadn't flown in my last 20 days on reserve and also wasn't the next in line to be called. I felt like granting my request would have been a pretty safe gamble.
