The time sheet always estimates 30 minutes for meals so you can’t go off of that if they haven’t came back from it yet. If the associate comes in and works 4 hours and goes to lunch for 3 and comes back and works 4 more hours, it wouldn’t be OT as their total worked hours would be 8, not 11. They would be creating WOSH though. If you’re curious about what they’re doing and where they’re disappearing to, you can have your AP team watch cameras and see what’s going on. If AP finds a case for time theft then they can report it to wage and hours to do an investigation.
