More working days for sims

Hi everyone,
I've been thinking about sims working days.
At the beggining of their career sims work 5 days per week, but when they reach levels 7-8-9-10, number of their working days is reduced to 2-3 per week.
Is there any mod or solution so I can send them to work every day? It would be interesting for the story, and, of course, so they can earn more money...
Thanks
