Dear …
Thank you for your valuable contribution to our annual conference. I know that I also speak for others when I say that I found your approach to the management team this year to be very commendable.
You demonstrated great leadership qualities by allowing your managers to speak candidly without fear of reproach. Your willingness to participate at a team member level was very refreshing. The questions that were raised and the honesty that was exhibited in the room made for a very productive program. As our leader, you have set a good example for all of us to follow and I am certain that the pay-off will be huge as a result.
Thank you your time and your dedication in taking our company to great heights.
Sincerely,
