Unpleasant naval jobs and automated maintenance in Azur Lane

Apart from logistics, what would be the worst job in an organization such as Azur Lane?

Cleaning jobs are obvious candidates, while automated ships shift difficult work toward technicians, factories and the systems that maintain the machinery.

Unpleasant jobs in a fictional navy are compared with routine work in real navies. Radar watchkeeping is treated as boring for some people, while bilge and sewer cleaning supply less appealing examples. Azur Lane's mass-production ships are distinguished from crewed warships because they are fully automated. That removes a shipboard crew's burden but leaves work for technicians and whoever maintains the repair facilities. Even an automated factory needs monitoring and maintenance of its own machinery. Fault-finding in a complex automated shipyard is therefore presented as a potentially difficult support job.
