A job is where Pops work to produce resources on planets. Jobs are divided into different strata, with one higher than the other. Most Jobs are created by Districts and Buildings and thus limited in number.
Pops will automatically fill empty Jobs that they are capable of holding and will choose the job that will get the most out of their traits based on a weighting system but priority can be set towards and away from specific Jobs to ensure they are filled before others. New Pops that are more suitable for a Job than the current Pop holding the Job may take the job from it. It is possible to force a re-evaluation of jobs by blocking and then re-enabling the jobs.
Regular empires have three strata. If a pop takes a job above its stratum it will be promoted to the higher stratum. If there are no available jobs of equal or higher Stratum the pop will become unemployed, slowly demoting in stratum and causing happiness penalties at most levels of living standards.
For Specialist jobs new pops will only take the job from a current pop if the new pop's weight is x1.5 higher.
Slave Jobs can only be worked by Pops belonging to species that are enslaved.
Pops that do not have a Job, either because none is available or because their Stratum is higher than that of available Jobs, are Unemployed. Unemployed Pops produce the following and cannot have their output improved by modifiers:
|Social Welfare||+1 Unity|
|Shared Burden||+1 Unity|
|Hive Mind Drone|
|Machine Intelligence Drone||-75% upkeep cost reduction|
Pops that have the Undesirable Stratum due to being purged produce resources as they decline based on the purge type. All Purging Jobs also produce +2 Unity if the empire has the Fanatic Purifiers civic.
|Necrophage||−50%||Pop becomes primary species after 10 years|
|Extermination||−1000%||+2 Unity if Determined Exterminator|
|Chemical Processing||−1000%||+6 Energy|
High Crime, Deviancy or Unemployment can create planet modifiers that add Subversive Jobs. Individualist Pops will abandon Subversive Jobs if Ruler, Specialist or Soldier jobs become available. All Subversive Jobs have negative output.
|Criminal||−1 Trade Value||Criminal-related planet modifier||These criminals live outside the bounds of legal society, some by choice and some by circumstances.|
|Deviant Drone||−1 Energy||Drone Deviancy planet modifier||These deviants no longer obey the Hive Mind.|
|Corrupt Drone||−1 Energy||Drone Corruption planet modifier||These drones have been corrupted and no longer obey the directives of the core intelligence.|
Event jobs are generated by either planetary features or planet modifiers.
Primitive civilizations use the same strata system as normal empires but their jobs provide negligible output.
Fallen empires use a special set of high-output jobs that have no upkeep.
