There's already at least one job that has 24/7 hours, meaning the PCs who work there can have more flexibility in when they can work and when they can RP outside the job, as well as earn more income than PCs who have jobs that only pay during IG daytime.
Let the other jobs be the same, so that if a player only has three hours to game in the evening after their RL job, and those three hours are during IG nights, they're not forever locked out of being able to work IG.
