Departmental meetings can be very productive. Here are two things to avoid and two things to create for effective departmental meetings.
1. Avoid department meetings were the supervisor talks down to everyone.
2. Avoid department meetings where the supervisor tells everyone what to do.
3. Create department meetings where everyone has shared input into the success of the department.
4. Create department meetings where everyone's ideas are valued by sincerely listening to and seeking to implement their ideas.
