This year is the second year of unrestricted Boxing Day trade in NSW.There will be a report in the new year as to whether it continues.
Prior, the rules allowed hospitality, and retail in "tourist" areas, but other retailers were regulated to be closed.
The argument for it is convenience and a vibe of increased custom. The argument against is that the increased custom would occur on other days and people should have a two day break at Xmas.
My own view is that the convenience is useful, but I can see a two day break is very desirable. I think the increased custom idea is nonsense - I don't suddenly have more money to spend if the shops are open.
Our family has some retail workers who would have been able to attend Xmas events if they had two days who missed out (because they had to travel far enough to make an overnight necessary).
So I will vote have two days, because of that (disclosure). I personally have a couple of weeks off, and my employer almost insists on a week off, which is another question.
I dont work in retail but i had to work christmas, boxing day, new years day, australia day.
Point im making is sometimes it just had to be done. Bills gotta be paid.
