Well, for me it's two major things....



 Being kept "in the loop" about what's going on.  This tells me that my job is recognized and important.  I like to know what part my tasks have in the bigger picture.  



Attitude is, of course, very important and it's a bunch of little things like making eye contact when speaking to me or letting me finish what I am saying without cutting me off or butting in (hate that!), or speaking to me without "dumbing down" your vocabulary (I'm quite conversant in English, thank you.)
