Shifts
A shift is a named working window — start and end time, break minutes, expected paid hours, a late-grace window and the weekdays it runs — reused across everyone on it.
Clock-in
Employees clock in and out against their assigned shift; worked minutes are the clock pair less the break, and a late clock-in past the grace window is flagged automatically.
Register
A 30-day register shows every person's day with check-in, check-out, worked hours and a status of present, late, half-day, absent, on-leave, holiday or weekend.
Corrections
HR can add or correct a record by hand — a manual entry overrides a missed or wrong clock, and every change is recorded in the audit log.
