Your Lady needs financial stability. It's good for her to provide for herself and maintain a high level of professional competence. To achieve this, she has to go to work, so that she can earn enough money to maintain her desired lifestyle and wardrobe.
Your Lady must complete a job course in the Employment Agency in order to be able to work.
All kinds of work are paid per hour - even if you go to work for one hour, you get paid. You can choose the duration of your work day - from 30 minutes up to 8 hours. Still, you don`t want to totally exhaust her - she needs to have free time left for dancing ;)
