The correct solution to that would be to hand some collective ownership and responsibility to the employees of a store. Make schedules public, or if that's a privacy issue (I don't think it should be), at least discuss overall statistics at some regular meeting. "Hey team, we worked x hours this month, and our best employee worked 96 ours of overtime! Amazing!" In your example, the "individual [having] an outsized effect on the group" is the store manager. They need some oversight to ensure they're correctly wielding their power over the timekeeping system and their employees. You could have the next manager in the chain conduct oversight, but then you might end of with the same issue. Better to distribute power to the employees, so no one person can ruin the store, and everyone feels a little more responsible and important.
