Shift Scheduling & Compliance: A standard 12-hour shift schedule is structured to satisfy workplace production requirements while complying with Fair Labor Standards Act (FLSA) guidelines and state rest period mandates.

Unpaid Meal Deductions: When employees take an uninterrupted meal break of 45 minutes or more, this interval is deducted from the total elapsed shift time. If an employee punches in at 07:00 AM and punches out at 07:45 PM, their gross on-site presence spans 12.75 hours, resulting in exactly 12.00 net payable hours.

Payroll Automation: Time and attendance systems record timesheet intervals in decimal hours (e.g., 12.00 hours). Multiplying these net payable decimal hours by the agreed hourly rate provides accurate gross compensation without rounding discrepancies.

FLSA Payroll Advice: Always check whether your state requires mandatory unpaid meal breaks after 5 or 6 hours of continuous labor. Accurately deducting meal breaks ensures zero discrepancies between logged shift durations and gross pay stubs.
