Tell it like it is!

tell it like it is

To speak bluntly, directly, and truthfully, even if what is being said is undesirable to the listener. I always respect employees who are willing to tell it like it is, rather than trying to sugarcoat everything to save a little face. I tell it like it is, and that rubs a lot of people the wrong way.
