When Jerry Maguire was forced out of his sports management agency that he helped build (it’s a fact) in a very public, humiliating way, he reminded some several dozen of his colleagues that “there is such a thing as manners; a way of treating people.”

It was true then, and it’s true now: with colleagues, with clients, with customers…a little professional etiquette goes a long way, and it’s more than good manners, it’s good business.

So, all lecturing aside, if you’ve got an iOS device and three hours to spare, why not dive into PRDV104: Professional Etiquette on iTunes U?

Take a look at Professional Etiquette and let us know what you think. Not on iOS? Not a problem! PRDV104’s got a permanent home on Saylor.org, too. We’ve got 37 other courses to enjoy on iOS (including three more professional development courses), and all of those plus 244 more to enjoy at Saylor.org via your favorite browser. Enjoy!
