I made my first mod that enables the "work from home" option for the writer career. Working from home has the same mechanism that came with City Living careers. You will get a notification 1 hour before work where you can choose from sending your sim to work, working from home or taking PTO. Then you get two assignments if you choose the "work from home" option. Most of the assignments are the same as other careers' (social media, critic, activist), but there are some new tasks, especially after choosing a branch for your sim.
Below there are a few examples of the daily assignments.
