How do you take vactions?

There is absolutely no option to call for vacation days or maternity leave. Those may have been added to the game but they are so faulty and glitched that the only way is to still have a sim who knows enough in the writing skill to fake a note for your other sims. Multiple times now I've been told both my sims could take time off for maternity or they have been complaining they want a vacation and no matter what I do I cannot get this so called Use Vacation Day option
