How to Level Up Jobs
The way that jobs level up is that it is based on actions taken. For instance a character taking 5 actions a battle will have their job level increase faster than a character taking only 2 actions a battle. An easy way to level up jobs is to fight a battle, guard 9-10 times (these will count as actions), then finish off the enemies. You should have everyone's job level increase every time you do this.
