Quick contract/inverse assignment question?

I checked the PWA on this and either couldnt find it in section 23 or maybe it is not in the new PWA. (new PWA is posted on Deltanet)

Last month I was a lineholder and was given an Inverse Assignment on one of my off days, .....so do they need to give me a payback day for the day I flew?

I checked my icrew and there is no payback day in there that they owe me, but again not sure if they owe me it or not.


Thanks in advance,
P
