Adult Sims go to work at 9 AM to 12 PM. Teens and Elders go to work at 10 AM to 12 PM. Orangutans go to work at 11 AM to 2 PM. Castaway careers don't have specific days-off and vacation days, therefore Sims can't call in sick. On the other hand, there is no penalty if Sims don't leave for work either. Sims have chances for two times to go to work if they happen to be unable at the first chance.
