Hall County officials met with representatives of ADP, the nation’s largest payroll services provider, last week for informal talks about how the company might improve the way checks are processed and cut for some 1,600 county workers. Officials have previously discussed reducing the number of pay periods for employees as a way to save money.But addressing inefficiencies in the way work hours are tallied could be the cost-cutting solution officials are looking for. Human Resources Director Bill Moats has said there is no consistent method across all county departments for tallying employee hours, and more than 60 timekeepers are charged with tracking and processing hours logged.
