Maybe you're a hugger, or a back-slapper, or -- in your personal life -- a terrible flirt. Chances are, you know that none of this behavior will fly in the office, no matter how innocent your intentions. No one wants to be referred to HR for remedial training or, worse, lose their jobs because they didn't get the memo that it's 2015, and co-workers don't touch each other. In this, we are probably more with the program than many of our leaders in Washington. Take, for example, America's touchy-feeler-in-chief, Joe Biden.
