I think the vast majority of this thread agree with you that what we saw in the article was incredibly dangerous to the employee.

In my example these sites are unmanned 99% of the time but if there was an operator on site and someone back in the head office went on the loud speaker to tell off some trespassers I can't imagine OH&S or the on-site operator would be the slightest bit impressed.

Yeah of course, that's why I said it's a very good plan :-) in your example it makes perfect sense.
