Would you like having part time careers in the game?

I'd like for adults to have part time jobs, especially for my YA sims because sometimes it feels weird to just put them in a lifelong career right away. For some of my sims, it doesn't matter, but the option would be nice. I'm a bit afraid to mod my game because when I did it with sims 3 the whole thing crashed and just kinda turned me off to the whole thing.
