Others gave the correct answer, but PWA 23.S.9.e is your reference.

As far as no-showing a rotation, I’ve done that probably 4-5 times over the last 2 years. Once scheduling finally calls you (usually around D30), it takes them 5-10 minutes to dig in and figure out where they screwed up. Once that happens they just remove the assignment and place you back on LC. Never once have I received a follow up call from the CPO.
