They have not been able to look and try to solve the problems in department 2 because there is no manager in department 2 and department 1 is also very busy so the manager for department 1 is too busy with his department 1 work that he cannot help out department 2.は 課長が2課にはいないのと1課が凄い忙しいせいで、1課の部長は1課の仕事に追われてしまい、二課の管理は全く出来ておりません。ですから、二課の問題は後回しにされてしまうと言う意味です。
