Mondelez is a payroll system case in practical clothing. Everyone knew the Fair Work Act said 10 days of paid personal/carer's leave. The fight was about what a "day" means when employees do not work ordinary 7.6 hour days and a missed shift may be 12 hours long.
For employers, the story is painfully familiar: a payroll setting that looks technical can turn into a major legal question. Leave accrual needs to be checked against the National Employment Standards, the enterprise agreement, the roster pattern and the way balances are shown to staff.
