That is coming from this mod, yes. You can deactivate it in your settings file ("The Sims 4\saves\Kuttoe\[Kuttoe] CareerOverhaul_Settings.cfg") by opening it and changing "coworker_toggle" to "false".
Oh awesome! Thanks so much! If you are interested in ideas for future versions, I wonder if it would be doable to have jobs harder to get initially too, such as needing to attend an interview. Anyways, thanks for getting back to me and solving this little issue for me, aside from that, this mod along with a few others have really helped me enjoy the sims 4 again, you are a star!
