He, like all actors, are paid pursuant to contract (whether the basic production contract or his undoubtedly specially drafted one). In that contract he would be entitled to certain paid time off. Keeping tabs on other folks' leave accounts is not something I do, so I don't know, but my guess is he still has ample leave that he has not used. So, unless my guess on that is wrong, and I doubt it is, he would not be "docked." "Dock," in the employment context, refers to a punishment. I can pretty much guarantee you that no one is punishing him. And if for some reason he would need to miss more than the contemplated amount of time, something would be worked out. One can buy insurance for this (as one can for anything) but it is (a) pretty expensive and (b) probably subject to a deductible that would far exceed the "shortfall" the production experienced.
