Leadership is hard. HR is hard too. That's no excuse to be defensive, crabby or no fun to be around at work. I came across this graphic while cleaning out some files.
As HR professionals and leaders, we are working with people. Yes, half the time they may irk you but the other half of the time you are driving them nuts. Get over it.
Be good to yourself and others.
