It (sort of) says here.
In fact, PR doesn't appear anywhere in the list of 10 ten jobs.
Running your own business is number one.
Least favourite jobs were politicians, plumbers and dentistry.
In addition, the Reed Employment sponsored survey found that: "despite the increased pressures upon companies to improve their brand image and act in a social responsibility (tut, tut, where was the proof reader) way, corporate reputation has very little influence over a job seeker. Just 6% of respondents would select a company because of its corporate social responsibility programmes and only 2% stated they would be swayed by an employer’s brand image."
Perhaps all those references to PR supporting brand building for recruitment purposes need to removed from agency credentials?
