There's good and bad in everyone, it's subjective and a matter of perspective but what people see, how they react to it, isn't always valid and some see bad where it doesn't exist due to disgruntlement and other such things; this is something most leaders will face at some stage whether it's professional manager or leader, sporting coach, school teacher and even family...anywhere a person leads, guides and directs others. It's not always the leader's fault that they're seen as bad although it's always the leader's responsibility to deal with the ramifications of that in the most productive and effective way.
