seagull manager
カモメのようなマネージャー
社員が問題を起こしたときや、仕事のミスをしたときだけ、その社員の所へやって来て、ガミガミ言う管理者。
A seagull manager is a manager who only meets and speaks to his employees to tell them what they have done wrong and that they are not doing a good job.
He is compared to a seagull, because, like a seagull, he flies in, makes a lot of noise, shits on everything, and then flies away.
