Who are you ignoring?

Strange question...but I bet they work hard, never complain, do a good job, good team player?
You see we spend loads of energy on the bottom 20% of employees in pep talks, disciplining, in managing....this is often to the neglect of the good old fashioned worker! Look round have you told them that you value them, have you told them that you appreciate their hard work...you see thy DON'T MOAN, so they will rarely tell you when they are not happy they will just resign.
Don't allow those Invisible employees leave - they are very difficult to replace......tell them you care!
