How does lunch time work for salaried non-exempt employees?

Employees do not need to clock out/in for lunch. They are guaranteed 8 hours of pay each day, unless you work out a flex schedule with them. If they work through lunch and this results in a total of hours worked, vacation, and sick time in excess of 40 hours in the work week they must be paid overtime. Working through lunch is a case in which advance approval should be required.
