Tired of losing co-workers to other "jobs"?

I have been frustrated playing sims who are forever losing co-workers to showtime careers. After looking all over the web and finding no real solution other than major tweaking with one NRaas mod that still didn't guarantee no co-worker loss, I tried a simple solution.

I created a household of eight NPCs with random traits and gave three of them the LTWs that would ensure they would want to be a singer, magician, or acrobat. This worked for me as I saw the random sims around town doing "acts" and my sims were able to progress all the way to top in both their careers without losing a (young) adult co-worker. One sim in the sports career lost one co-worker once, but I think that was an elder sim. Any way, sometimes there are simple fixes we don't think. 

I know other sims have looked for a solution barring uninstalling Showtime, so I thought I'd share this idea.

Happy simming.
