Not being responsive to questions or requests. When an employee asks a question or makes a request, don’t ignore it until they have to ask again. Be responsive – yes, no, maybe, or let them know when you will have an answer for them.
Forgetting what you have asked them to do. Yes, we all forget now and then, I know I sure do. When you do, it tells your employee what you asked them to do may not really be that important.
Assigning the same task to different employees. This could happen due to forgetfulness, or it could be setting employees up intentionally to compete. Both are annoying.
Not setting an example (do as I say, not as I do). Leaders need to be role models, not hypocrites.
Taking special privileges. For example, flying first or business class and having your team fly coach. There is a great leadership tradition in the military – officers eat last. It’s a good standard for corporate managers to keep in mind.
