I'm on reserve for the first time in a long time, so this is new to me:

I've been getting "inverse assignment" robocalls at zero dark thirty on my days off. Notwithstanding that it's ridiculous to think that anyone could answer the phone at 0200 and be ready to check in at 0530, how would picking up an inverse assignment even work while on reserve? Would I get double pay, over and above my reserve pay? Would I get double credit toward my reserve commitment? What's the deal?
