Some of my Sims no longer have an ideal mood to boost their work performance.
The ideal mood was removed for all non-active careers in Patch 1.47.49.
To boost your performance, simply make sure to send them to work in a positive mood.
1) "Ideal Mood" has been removed from career progression for non-active careers. You can send your Sim to work in any positive emotion to help increase your Sim's job performance.
