If paid fortnightly, annual pay is calculated as:
$ fortnightly × 26.08333333...
Why? Every year there are 52 weeks plus one day (or two days in a leap year); this works out at 313 pay periods over 12 years. Therefore:
$ fortnightly × (313/12)
Howard's disastrous industrial relations "reform" package promises to make working conditions worse while decreasing pay.
