According to research by leadership experts Jim Kouzes and Barry Posner, honesty is the most important attribute Americans look for in their leaders. It comes before “forward-looking,” “inspiring” and even “competent.” What a shame that it so often takes a dramatic exit for those in power, and for all of us, to say what needed to be said all along.

Following his firing, Mason, who is also one of Groupon’s co-founders, shared this note with employees that seems as self-effacing as it does sincere. Here is what he wrote:

People of Groupon,

After four and a half intense and wonderful years as CEO of Groupon, I’ve decided that I’d like to spend more time with my family. Just kidding - I was fired today. If you’re wondering why... you haven’t been paying attention. From controversial metrics in our S1 to our material weakness to two quarters of missing our own expectations and a stock price that’s hovering around one quarter of our listing price, the events of the last year and a half speak for themselves. As CEO, I am accountable.

You are doing amazing things at Groupon, and you deserve the outside world to give you a second chance. I’m getting in the way of that. A fresh CEO earns you that chance. The board is aligned behind the strategy we’ve shared over the last few months, and I’ve never seen you working together more effectively as a global company - it’s time to give Groupon a relief valve from the public noise.

For those who are concerned about me, please don’t be - I love Groupon, and I’m terribly proud of what we’ve created. I’m OK with having failed at this part of the journey. If Groupon was Battletoads, it would be like I made it all the way to the Terra Tubes without dying on my first ever play through. I am so lucky to have had the opportunity to take the company this far with all of you. I’ll now take some time to decompress (FYI I’m looking for a good fat camp to lose my Groupon 40, if anyone has a suggestion), and then maybe I’ll figure out how to channel this experience into something productive.
