Running a club sucks. In a nutshell the only way I see that it works is a dictatorship, no vote system that is upfront, and honest with set rules.
As far as getting members to work. Couple things that I have seen work. Set missed work day fees to high $$.Create a list of completed work days per member. In ascending order, the members that complete the most work days get first dibs on signing out opening weekend of bow and rifle season. Those members that opt to sit at home all offseason and not participate will have to deal with the leftovers for those first couple weeks.
