Rule priority

Process rules in this order:

1. Qualifying sleepover rules.

2. Broken-shift validation and the 12-hour broken-shift boundary.

3. Day-worker span and shift-worker status.

4. Daily ordinary-hours boundaries.

5. Full-time daily authorised work outside rostered ordinary hours.

6. Part-time daily thresholds and agreed-rostered-hours threshold.

7. Casual daily threshold.

8. Part-time and casual weekly and fortnightly thresholds.

9. Selected ordinary-hours model and roster-cycle boundaries as boundary controls.

10. Assign all remaining Unallocated_Hours to Ordinary_Hours.

Where multiple rules identify the same worked hour:

• Assign the hour to Overtime_Hours once.
• Remove it from Unallocated_Hours.
• Do not create a second overtime allocation for the same hour.

Pseudocode

• Initialise hours

  Worked_Hour_Units = split each shift into non-overlapping hour units
  Unallocated_Hours = Worked_Hour_Units
  Overtime_Hours = empty
  Ordinary_Hours = empty

• Select and record the ordinary-hours model

  IF Applicable_Ordinary_Hours_Model = "38 hours per week":
      Ordinary_Hours_Model_Boundary = 38 hours per week

  ELSE IF Applicable_Ordinary_Hours_Model = "76 hours per fortnight":
      Ordinary_Hours_Model_Boundary = 76 hours per fortnight

  ELSE IF Applicable_Ordinary_Hours_Model = "114 hours over 21 days":
      Ordinary_Hours_Model_Boundary = 114 hours over 21 days

  ELSE IF Applicable_Ordinary_Hours_Model = "152 hours over four weeks":
      Ordinary_Hours_Model_Boundary = 152 hours over four weeks

  ELSE:
      flag missing ordinary-hours model

  // Clauses 22.1 and 25.1
  Calculate Outside_Ordinary_Hours_Boundary using the selected model.
  Do not classify an hour as overtime from this boundary alone.

• Apply the 28-day roster-cycle boundary

  // Clauses 22.1(a) and 22.1(b)
  FOR each 28-calendar-day roster cycle:
      IF Roster_Cycle_Work_Day_Arrangement = "20 work days":
          ordinary roster-cycle arrangement = no more than 20 work days

      ELSE IF Roster_Cycle_Work_Day_Arrangement =
              "19 work days plus accrued paid day off":
          ordinary roster-cycle arrangement =
              no more than 19 work days plus twentieth day as accrued paid day off

      Mark work outside the selected arrangement as Outside_Ordinary_Hours_Boundary.

  // Clauses 22.1(a), 22.1(b), 25.1
  Do not classify roster-cycle boundary hours as overtime unless a cohort-specific
  overtime trigger below also applies.

• Apply the daily ordinary-hours limit

  // Clauses 22.1(c) and 25.1
  FOR each employee and calendar date:
      IF Shift_Type = "day shift":
          Daily_Ordinary_Hours_Limit = 8 hours
      ELSE IF Shift_Type = "night shift":
          Daily_Ordinary_Hours_Limit = 10 hours
      ELSE:
          flag missing shift type

      Mark hours after Daily_Ordinary_Hours_Limit as
      Outside_Ordinary_Hours_Boundary.

  Do not classify hours after the daily limit as overtime from this boundary alone.
  Apply the employee’s applicable cohort-specific overtime trigger.

• Identify day workers and shift workers

  // Clauses 22.2(a) and 22.2(b)
  IF Shift_Worker_Status = "shift worker":
      Employee_Cohort includes Shift_Worker
  ELSE:
      Employee_Cohort includes Day_Worker

  // Clause 22.2(a)
  IF Employee_Cohort includes Day_Worker:
      Mark hours worked before 06:00, after 18:00, or on Saturday/Sunday as
      Outside_Day_Worker_Span.

  // Clauses 22.2(a), 22.2(b)
  Do not use the day-worker span as a standalone overtime trigger.
  For a shift worker, do not apply a separate shift-worker span because the source
  does not specify one.

      IF Daily_Worked_Hours > Daily_Sleepover_Comparator:
          Identify the portion of the relevant day's worked hours
          exceeding Daily_Sleepover_Comparator.

          to Overtime_Hours.

      IF Fortnightly_Worked_Hours > 76 hours:
          Identify hours exceeding 76 hours in the relevant fortnight.

          record broken shift as valid

      ELSE:
          flag broken shift as not compliant with the reviewed conditions

• Broken-shift span exceeding 12 hours

  // Clause 22.8(d)
  IF Broken_Shift_Span_Hours > 12 hours:
      mark hours beyond the 12-hour broken-shift span as
      Outside_Ordinary_Hours_Boundary

      // Clause 22.8(d) is not a standalone overtime-hours trigger.
      Do not move these hours to Overtime_Hours unless the employee's
      applicable overtime trigger below is also satisfied.

• Full-time daily authorised work

  // Clause 25.1(a)(i)
  IF Employee Type - Full Time/PartTime/Casual = "full-time":

      FOR each calendar date:

          the employee's rostered ordinary hours for that date.

          IF Authorised_Work_Indicator = TRUE:
              Move only those identified hour units still in Unallocated_Hours

Conditions not considered by the pseudocode

• Clause 22.1
• Business rule: the applicable ordinary-hours model may be 38 hours per week, 76 hours per fortnight, 114 hours over 21 days, or 152 hours over four weeks.
• Reason not directly determined from available fields: the selected model is an employee or work-arrangement configuration not contained in the supplied fields.

• Clauses 22.1(a) and 22.1(b)
• Business rule: the 28-calendar-day roster cycle may contain no more than 20 work days, or 19 work days plus an accrued paid day off on the twentieth day.
• Reason not directly determined from available fields: the roster-cycle arrangement and accrued paid day off are not supplied.

• Clause 25.1(a)(i)
• Business rule: full-time overtime requires authorised work in addition to rostered ordinary hours.
• Reason not directly determined from available fields: authorisation is not represented by the supplied fields.

• Clauses 10.3(b), 10.3(c), and 25.1(b)(iii)
• Business rule: part-time hours above agreed daily rostered hours are overtime unless a documented written variation exists.
• Reason not directly determined from available fields: the documented written-variation status and agreed rostered hours are not fully represented by Roster_Start and Roster_End.

• Clauses 22.9, 22.9(a), 22.9(g)(i), and 22.9(h)
• Business rule: a qualifying full-time sleepover must be an 8-to-10-hour overnight required sleepover, immediately before or after the shift, with continuity permitted where applicable.
• Reason not directly determined from available fields: sleepover status, on-call emergency requirement, sleepover duration, and continuity permission are not supplied.

• Clause 22.9(g)(ii)
• Business rule: permanent part-time sleepover overtime uses the full-time employee daily-hours comparator, or 11 hours if no full-time employee exists.
• Reason not directly determined from available fields: the system-recorded full-time daily comparator and permanent part-time status are not supplied.

• Clauses 22.9(g)(iii) and 22.9(k)
• Business rule: casual sleepovers are permitted only where full-time and permanent part-time employees are unavailable and not where the casual is used exclusively or almost exclusively for sleepovers.
• Reason not directly determined from available fields: employee availability and the casual employee’s sleepover usage pattern are not supplied.

• Clauses 22.8(a), 22.8(b), 22.8(d), and 22.8(f)
• Business rule: a mutually agreed broken shift requires non-meal breaks of no more than four hours, compliant minimum engagement for each portion, and a span of no more than 12 hours; work beyond 12 hours is subject to a payment consequence but is not independently an overtime trigger.
• Reason not directly determined from available fields: broken-shift agreement, break classification, minimum-engagement compliance, and total broken-shift span are not supplied.

Implementation notes

• The Outside_Ordinary_Hours_Boundary field must not independently create overtime because clauses 22.1, 22.1(a), 22.1(b), 22.1(c), 22.2(a), and 25.1 require the applicable cohort-specific overtime trigger to be satisfied.
• Shift_Worker_Status should be used to identify shift workers. The source provides no separate shift-worker ordinary-hours span.
• Public_Holiday_Indicator, Previous_Shift_End, and Shift_Day do not create overtime under the reviewed rules and are not used as standalone triggers.
• The broken-shift rule must not classify hours beyond 12 hours as overtime solely because clause 22.8(d) applies.
• Sleepover hours must be included in the relevant daily, weekly, and fortnightly totals before applying the sleepover-specific thresholds.
• Apply the relevant weekly and fortnightly thresholds to the same worked-hour population only once. When a daily and a weekly or fortnightly rule identifies the same hour, retain one overtime classification.
• Do not calculate overtime multipliers, double-time amounts, penalty amounts, allowances, or other payment outcomes.
