in answer to your question- at PNCL the clock starts when you either answer the phone OR they leave a voicemail. So if you are in the shower- and they call as soon as you get in, call them back 15 min later when you get out- you now have 75 min left. But watch how you work it, I had a couple instances where scheduling would call before my rsv period started and try and give me a flight that was not for my rsv time. If you are not on rsv or on duty DO NOT answer the phone- listen to the voicemail, but only call back if it benefits you. Your earliest show time for example of a 8-8rsv period is 9:30. Example of what they will try... There is a rsv period of 5am-5pm and 8am-8pm. They may have run out of the 5-5 guys and its 6:30am at the moment, so they will call the first guy on the 8am time. If you answer they will try and tell you to be there in 90min (8am). You will have a long argument to get them to not assign it once you have answered because technically you are notified. DO NOT call them back til 8am! From 8am-8pm you are their "puppet" 6:30am is still YOUR time. You can go online and see what they put on there, sometimes you see an 815 show and you will be done and released by 1pm if you take it- then it may benefit you to call and check in to take it caus e you can get released to go home on the 2:30 flight instead of waiting till 9:30 at night. The system can be worked IF you know the contract. NEVER answer though unless you know you must- your rsv time or on duty. Otherwise see what they are trying to do. Remember, they are just trying to do their job covering trips- sometimes "bending" the rules hoping you will go with it. Sometimes "going for it" can help you out. WHATEVER YOU DO do not answer your phone on your day off- 98% chance its a junior man assignment. I was on rsv for 4 months so I learned how to make it work, chances are you will still be on probation so you don't want to end up in shouting matches with schedulers, but if you don't answer the phone when you don't have to there will be no arguments to be had.
