Meetings are important, but last minute meetings can disrupt time management. There are times when there must be a last minute meeting, but make sure that all meetings are productive to the individuals who attend. I have found that most meetings are unproductive even if they are scheduled. Most of the information can be placed in an email or sent through an interoffice memo. People must remember that wasting your time is your business, but wasting other people's time is disrespectful.
