Worth reading the whole article; it makes it quite clear that you have to be sure that hugs are acceptable and welcome in the workplace.
Its also dancing around the fact that it is not considered professional behaviour.
There has been lots and lots and lots of material written about managing one's career. Harvard Business Review, Forbes, HR Journals, MSN Careers, countless others....I can't remember any that said hugging and touching in the workplace is a positive thing for one's career. Especially as jobs have gotten harder to come by. The Career Builder article talks about the physical benefits of a hug being stress relief and all that. Personally I think having the folks around you disciplined to focus on their job and excel at it is far better workplace stress relief than any of the touchy-feely stuff.
Yes, in some environments you may be able to get away with hugging, but IMO a far better career decision would be to choose excellence over mediocrity (or worse).
