Grown-ups shouldn't need praise for doing what they've been hired to do. To me, if an employee does something like hand in a report to a supervisor, a simple "thank you" is fine (or maybe something like, "This looks good." - if, in fact, it DOES look good). That's simple courtesy, and if the boss hands the staff member something like a set of statistics, the staff member ought to say, "Thanks," or something like, "Thanks for getting these to me this soon," too. As for "praise", though - no. Employees aren't children. If they want/need praise they're most likely going to be bitterly disappointed in the work world (or in any world, for that matter). :) Respect and general appreciation for doing the job well is all anyone should need (and the appreciation can be demonstrated at review time). Respect should be shown all the time; and as far as I'm concerned, if a supervisor thought I was so childish that I wanted/needed praise, I'd see that as "lack of respect" for me, as an equal adult.
