This is from the writer's guild strike rules, #12 (this was posted in another forum)
Hyphenates (i.e. members employed in dual capacities such as writer-director, writer-producer, etc.) may not perform any writing services,
“(a) through (h)” services, for a struck company. The MBA defines “(a) through (h)” as follows:
(a) Cutting for time
(b) Bridging material necessitated by cutting for time
(c) Changes in technical or stage directions
(d) Assignment of lines to other existing characters occasioned by cast changes
(e) Changes necessary to obtain continuity acceptance or legal clearance
(f) Casual minor adjustments in dialogue or narration made prior to or during the period of principal photography
(g) Such changes in the course of production as are made necessary by unforeseen contingencies (
e.g., the elements, accidents to performers, etc.)
(h) Instructions, directions, or suggestions, whether oral or written, made to a writer regarding story or screenplay"

So I'm not sure if they can change it, even if they did write it.
And yeah, where did the rest of my posts go?
