Hi
I have been reading this post with interest, and while I don't necessary agree with the definitions that CareyEaton has provided (I tend to think the ad is misleading), I am happy to accept his explanation and move on.
However, to add my two cents worth into the debate, I thought I would use some real examples from seek.
Have a look at the following link.
SEEK Job Search - Find jobs using multiple job search options
here, we can see three job ads which I think are identical (the clincher is the recruitment company reference number listed in the add - all the same number). Even if we accept CareyEaton's explanation that employers and agencies should be able to advertise one role in multiple formats, you could then potentially excuse the first one, but the second and third - they look like the same job advertisement to me.
In the past, I have also seen circumstances where recruitment agencies might periodically, say every week or so, relist every role they have, but then not delete the older roles that they had initially posted, thus leading to a duplicate, or they change a phrase like "inner city location" to "city fringe location".
I acknowledge that most of these practices probably wouldn't be in breach of the Trades Practices Act on misleading and deceptive conduct, but it is still conduct that I don't particularly like, and is very frustrating for job seekers...not that my opinion really means anything.
