The short answer is, absolutely nothing. But in my workshops, someone almost always asks, “Aren’t contractions forbidden in business writing?”
Recently, a client converted a print newsletter to online-only and banned contractions in all feature articles from the executive team and those by HQ on benefits and personnel matters.
Such pieces are typically dry even on a good day, so making their tone even stiffer and more formal — to be read on the easy, breezy Internet, no less — leaves me shaking my head.
Do you remember Data, the android on Star Trek: Next Generation? One of his biggest regrets was that he hadn’t been programmed for contractions, because he thought they’d make him sound more human.
When you eliminate all contractions from your writing, you sound like Data.
“We are happy to announce a new benefit that is most requested; you will be allowed to work from home on Fridays.”
“We are sorry for issues you have had with our website. It is our pleasure to make sure you receive service that is reliable.”
Simple contractions such as it’s and that’s definitely have a place in business writing. Just “listen” as you write and sprinkle contractions in where you would use them in conversation.
My only caution is to be careful if your readers speak English as a second language. In that case, you would want to keep the wording clean and simple to aid comprehension.
