Two large supermarket chains (gee, wonder which two that would be?) have branches in town.
On the recent Queen's Birthday public holiday, and all other public holidays, especially the Easter/Anzac Day week, the staff at each of the large supermarkets keenly anticipated the big money they'd get for working public holidays.
It was not to be.
Regular staff a each of these two large supermarket chains (gee, wonder which two that would be?) were miffed to discover they were not rostered on to work on any public holiday.
The work (shelf stacking, etc) was all done by juniors. Schoolkids who (of course) aren't at school on public holidays.
The public holiday rate for juniors is a whole lot less than that which must be paid to adults.
The supermarkets shafted their regular staff, but saved thousands of dollars.
So continues life for ordinary workers in a nation with prohibitive penalty rates.
