I have heard workers complain that their manager or colleagues do not trust them to make decisions.
It's easy for those with management positions in hierarchical organisations to be seduced into thinking that because they have a title and more pay they therefore know more about a subject.
This attitude can be a extremely demoralising for team members.
Others may have held leadership positions in other organisations and for one reason or another are now simply team members without a title.
You don’t have to know everything because you can’t.
When you are truthful about your own knowledge and ability you will be more open to learning from others, especially those in your team.
