This video has been on YouTube since the first of May. Interesting that HuffPo and Fox News and other outlets are reporting on the ghost video without reporting on the source of the ghost video. And basically it boils down to a PR campaign for a career placement service.
He says that it was supposed a warning against working late hours, but then he spends another minute and a half extolling the virtues of GMP's services. In other words, it was a PR stunt first and foremost.
[UPDATE 4:00 p.m.: HuffPo has amended their article. Now they give a link to this page that links to both the original video and the GMP response video.]
