As part of the Holidays Amendment 2010, there is a provision to allow an employee to have up to 1 week of current annual holiday entitlement paid out.
The main points are as follows:
The paid-out annual holiday must come from the entitlement year defined as:
When cashing out annual holidays, it is based on current entitlement for the current entitlement year, i.e. available annual holiday entitlements for the current entitlement year. It cannot be taken out of the previous year's annual entitlement or future entitlements/accrual amounts.
Example: The employee's anniversary date is 1 September (1/9), 4 weeks of annual holidays kick in on 1/9/19, and annual holidays cash out of up to 1 week can be requested using the 1/9/19 entitlement. The previous year's entitlement on 1/9/18 cannot be used, the future years yet to accrue in 1/9/20 cannot be used.
