Well, what if I I have been off for 4 days with plenty of rest and I get called for a JA? (Ex. Hey, can you make it to the airport in 2 hrs?), you mean to tell me I can't say yes?, I have to wait 10hrs?, that's ridiculous if that's how it is

The issue is, C/S doesn't "force" a JA on us,they call and ask "if" we can do it. When I have been JA, the conversation goes like this, "hey Joe, this is xxxxx from scheduling, are you able to do the MCO turn tonight, show time is 3 hrs from now?" - how is that "forcing"?
