Recently, there have been a few conservative executives warning their employees that there might be consequences if Obama was reelected. The Koch brothers even sent employees a list of candidates they supported. While not strictly illegal it is at least ethically questionable.
Turns out on June 6, Mitt Romney led a conference call with the National Federation of Independent Business where he suggested that tactic to the bosses in audience. The advice in question begins at 26:00.
"I hope you make it very clear to your employees what you believe is in the best interest of your enterprise and therefore their job and their future in the upcoming elections. And whether you agree with me or you agree with President Obama, or whatever your political view, I hope — I hope you pass those along to your employees. Nothing illegal about you talking to your employees about what you believe is best for the business, because I think that will figure into their election decision, their voting decision and of course doing that with your family and your kids as well."
