Saying thank you

A recent survey by U.S research company Vantage has found that what staff value most (even above a pay rise) is a "thank you" for a job well done. In my own experience, I have to say that managers seem to find it hard to say "thank you" or to show appreciation. Here are some expressions that you might hear if you're lucky enough to get thanks from your manager. I've also included some replies.

Thanking
Thank you very much for…
Thanks a lot for…
Thank you so much for…

… all your hard work
