The Job Adjustment Phase is a game balancing system designed to keep the player from rapidly switching jobs without consequence. This could make the game much easier by giving all characters access to healing or other beneficial spells outside of combat. Since the length of the phase depends on Job Level, it is also a way to encourage players to use a wide variety of jobs rather than switching to them only when needed, such as making a character a Thief just long enough to pick a lock and then switch back to their previous job.
