Origin
first recorded 20th c.The term became popular through a joke in Ken Blanchard's 1985 book Leadership and the One Minute Manager: "Seagull managers fly in, make a lot of noise, dump on everyone, then fly out."
The team felt frustrated because their seagull manager only visited the office to criticize their work after a project failed.
Rather than providing consistent guidance, the seagull manager arrived only to create chaos and leave, forcing the staff to clean up the resulting mess.
