In Oxygen Not Included, the Job Board allows a player to assign "Jobs" to the Duplicates (workers). This allows workers to gain experience doing various tasks, and with enough experience, they "Master" the job, which unlocks new jobs for them and gives them stat/skill boosts.
One can set the priority of the Job Board, but I do not understand what effect it has on the game. If I set its priority to 9, does that mean that all Duplicates assigned to a job will perform that specific Job, even though there may be other errands/tasks to do?
