Respectfully, this is totally contingent on how a staff runs their game.Yes the staff of the chapter essentially functions as employees, especially logistics, Owners, GM's, Heads of Rules and Player reps but their impact on the game really only extends to the periods in between games. From roughly 9:00 PM friday night to 12:00 Noon sunday we are all players and we are all responsible for making the game fun for everyone.
Example: at GB, I am literally on-call 24/7 in game while PCing. I invite PCs at the beginning of every event to seek me out if they are uncomfortable, unhappy, or just want to give me some feedback they're afraid they'll forget between game and when I send my survey. My impact is constant and immediate - if I take our players' temperatures and hear that things are running a little too slow or we don't have quite enough crunch for the folks who don't really come for the RP, it is my responsibility to get to NPC camp and say, "hey, how can we get some crunch out between mods for the folks who aren't presently being engaged by the main or secondary plots/the stick jocks?". I feel, personally, that if I have to wait a month to fix what is happening now, I have not fulfilled the requirements of my volunteer position.
I have seen this happen a lot at HQ this past season, too - with few exceptions, Donna and HQ plot/NPC camp have been really willing to on-the-fly adjust to the player feedback they receive within a given event - obviously, always within reason.
