It is interesting to note that people have heard these common sayings wrong so many times that sometimes the correct usage will sound incorrect. Watch (this is fun) some of your employees will look a little startled or confused and later you will notice them looking up the word or phrase on their cell phones or computer.

Whether you are saying these phrases to others in a meeting or casual conversation or you have used them in writing, make sure you are not embarrassing yourself by misusing these phrases but are, instead, going with the correct versions listed here.
