Look at the Reserve Gouge 5.5 sticky on the other forum.
You're on long call for the month until or unless you pick up or they assign you a SC for the following day. Long call callout is 13 hours.
Short Calls are typically published each day for the next day. This used to be done early each AM and the ones not picked up (at 1100) were then assigned by about noon. But, no more. Now they will frequently publish a few here, then a few there. This stinks because a guy junior to you might just wind up with the window that you wanted, but you jumped at an earlier window. This is a new and unwelcome change, particularly for commuters. Guys will claim that this is not new, but I submit they are mistaken because I was on reserve before they began this tactic.
At any rate, if you desire a SC you bid what you can hold within silo or silo minus one. IE a 4 day guy can bid a 4 or 3 day SC trip.
If you don't want a SC assignment, say on your last day of a stretch, you can almost expect them to build one just for YOU! Yes, you are that special. Expect it to be an early one, say 0800. That ought to tie you up for most of the day whereas if you were on Long Call, you'd effectively be done by 10 AM.
Call out time for SC is 2.5 to show, 3.5 to go. ADD PAY is optional for the company if a SC guy is able to beat the 2.5 hour limit, and it works for them.
SC window is about 15 hours. This allows 9 hours rest per 24 for FAR purposes.
SC's published in any given morning are available to be picked up (Aggressive Pick UP) buy long call maggots beginning at 1100 local.
As mentioned, first two SC's are freebies. SC's 3-4-5 are one hour ADD PAY each. I'll shoot you a PM regarding a few other tips.
Enjoy.
