Janitor

Janitors are workers who clean the trash by worker's desks. Janitors only come at night to clean. They can be promoted to clean more efficiently, and offices can be upgraded to Janitorial offices to help them clean faster, however, janitors do not need to be stationed at a desk that is in a janitorial office to be promoted. If there is too much trash next to a desk, it will cause workers to become unhappy, which lowers overall office happiness. People who need their desks to be rid of the trash are workers, accountants, researchers, and HRs.
