Minimum hours on public holidays
Regardless of how long they actually work, when an employee works on a public holiday, they have to be paid for a minimum of 4 hours of work.
Minimum hours on part-day public holidays
Minimum shifts or payments usually mean that an employee is entitled to be paid for a minimum number of hours per shift, even if they don’t work the full shift.
This will usually apply for every time an employee attends work, even if a shift is spread across a public holiday and a non-public holiday.
Substituting public holidays
An employer and an employee can agree to substitute a public holiday (or part-day public holiday) for another day.
If a public holiday is substituted, then the substitute day is regarded as the public holiday and penalty rates are only paid on the substitute day.
If both days are worked, employees can elect to be paid public holiday rates for the actual public holiday or the substituted public holiday, but not both.
