If an employee's hours are increased part way through the year, a pro rata manual adjustment will be required at the employee's Holiday Anniversary Date to take into account the period of the year their annual leave entitlement was less.
To work this out, make a note of the amount of time the employee was at the decreased/lesser hours, e.g. 24 hours a week, so 96 hours a year for 5 months, so 96 / 12 = 8 x 5 (months) = 40 hours.
If the employee increased their hours to 40 hours a week, this gives them an annual leave entitlement of 160 hours a year. But this amount would only be for 7 months (as the first 5 months, they worked 24 hours a week). So 160 hours / 12 (months) x 7 (months) = 93 hours.
Based on this calculation, 27 hours needs to be deducted from the employee balance. This is because MYOB Payroll has automatically calculated 160 hours of annual leave (based on the new normal hours per week, which is 40 hours), however the employee is entitled to 133 hours of annual leave (40 + 93 = 133 hours).
In Bill's example above, the Annual Leave due as at is sitting at 160 hours as per his new normal hours. However, Bill is entitled to 133 hours (40 + 93 = 133), so this amount needs to be changed to show the correct annual leave.
