We have good work days.

My favorite way is assigning areas to maintain.

Pay a fine in advance if you have no intention of working.
It doesn't bother me to do it for the older gentlemen who can't do that kind of labor.

I have seen a bunch of answers but the one that sticks out to me is reducing buck harvest for missed work days (... and add late lease payments to that too!) would seem to be a real attention getter.
