Not was I was told but ok.
Payroll is calculated based on a 45 minute lunch. If you work 5 days and do that you get paid for an extra hour and a quarter. Not a big deal if it's just you, but if the whole store does it payroll is blown. At my store if you do this you are talked to. I heard a srtl and hr talking about it when the srtl was clocking in under 45 minutes.
