Administration in general. There are so many jobs in (public and private) administration whose entire job is, to fill out forms or write reports, that nobody will ever read.
The same is true for countless middlemanager positions. It’s not a full-time job to manage 10 employees who are not directly working with you. No idea how this is called in other countries, but in Germany we call it Matrixorganisation, and it’s often as absurd as it sounds.
