Midnight Boundary Rules

Where a shift keyed against a timesheet crosses the date boundary between two days, midnight boundary rules are used to determine the da y type that applies to the shift. The day type allows Rates and Rules to determine if the date on which a shift occurred was a weekday, weekend or a holiday.
Multiple midnight boundary rules can be defined within each set of primary interpretation rules for a given agreement. For example, different midnight boundary rules may be created for weekdays and weekends or for specific days of the week. Different midnight boundary rules may also be created for days where a specific holiday type applies. If a holiday type applies to a given day, that day is flagged as being a holiday which may be treated differently for the purposes of pay interpretation when compared to regular working days.
A midnight boundary rule is created by defining a name that uniquely identifies the rule, the applicable boundary type and the shift day types
or holiday types to which the rule applies.
The boundary type defines if the midnight boundary rule determines the applicable day type by using the shift start date, the shift end date, the date on which the majority of the shift hours were worked or if the shift is treated as two separate shifts occurring on consecutive dates.
One or more shift day types can be selected within a midnight boundary rule if the rule is to apply to specific days of the week. For example, if a shift day type of Monday is selected, the midnight boundary rule will apply to any shift that starts on a Monday.
One or more holiday types can be selected within a midnight boundary rule if the rule is to apply to certain dates that are flagged as holidays rather than specific days of the week.
The following conditions apply to midnight boundary rules:
a single midnight boundary rule can apply to shift day types or holiday types but not both
multiple midnight boundary rules cannot be defined for the same shift day type or the same holiday type
where a midnight boundary rule exists for a given holiday type and another midnight boundary rule exists for the shift day type on which the holiday occurs, the midnight boundary rule for the holiday type overrides the midnight boundary rule for the day type
if one primary interpretation header is valid on a shift start date and another primary interpretation header is valid on the shift end date, the header that is valid on the shift start date applies to the entire shift, even if the shift is split for the purposes of determining the applicable day types.
