You'll know your schedule for the next day usually by noon or so the day prior. The one thing that can get ya is if they assign you short call. They still have to give 12 hr notice but if they notify you at 8 pm that you'll be on short call at 8am and your not in base already, you may not have a flight (s) to get you there.

On probation I would not chance sitting at home on reserve unless you live in or near base.

One thing you can do is a yellow slip. EX: You have 5 days of reserve starting tomorrow. You look in open time and see several 3, 4 or 5 day trips that start tomorrow. You can put in a request to pick up (yellow slip) a specific trip or a blanket request that could cover some or all of those open trips. If you see a 4 day for example that begins on the 1st day of your reserve and it reports late in the day, you could try yellow slipping it. If you get it, you are not required to be contactable prior to its report time. Good way to make reserve more commuter friendly.
