It's time for you to sit her down and have The Talk. During The Talk, you should outline all the hours you work, the fact that she's not even attempting to find a job, and the fact that she doesn't work means that she has plenty of time to do ALL the household chores, and that henceforward that was exactly what you were expecting of her, no excuses, period. If she's defiant about the situation, you should invite her absence. Enough is enough. Be part of the team, or be part of the trash. Trash gets thrown out.

'Nuff said.
