The reason people hesistate to share their observations about others' attitudes is that attitudes are subjective. Someone with a nasty attitude may not be doing anything illegal or unethical. Yet his or her attitude may be ruining the unity, the teamwork, the morale and hindering the vision and fruitfulness of the organization.
Attitude is really about how a person truly is.
And that overflows in how the person acts. Allow me to share with you a few rotten, contagious attitudes that, if left unchecked, can destroy the unity, teamwork, morale, vision and success of your organization. This will help you recognize such attitudes for what they are whenever you see them. It's pathetically painful and sad. Nobody's perfect, but someone who thinks he is doesn't make a good teammate.
