One other thing I found as a noob sitting on AA reseve... I lived fairly close to the airport, and crew schedule figured it out. Sometimes, I'd get an assignment where they wanted a warm body immediately, and since they knew my living arrangement, they skipped people and went right to me. This was back when there was actual seniority on reserve, and you could pass.

Just because I am the closest thing to airport standby, doesn't mean they get to violate the contract.

My point - once off probation, hold them to every single contractural item. Know your contract. And never volunteer the fact that "Oh yes, I live right next to the airport, I can be there in 15 minutes." You end up on some sort of secret "list.".
